Three-Dimensional Mechanical Information Model and Its Application to Large Underground Water-Sealed Storage Caverns for Oil or Gas

Abstract. The pumped discharge of groundwater increased rapidly in Japan during the period of fast economic growth since the beginning of the 1960s. As a result, land subsidence has been observed, including throughout the Nobi Plain. Laws have led to restrictions on the collection of underground water, and pumped discharge has gradually reduced. In recent years, the groundwater level that had formerly decreased has begun to rise again, leading to less land subsidence. However, as groundwater levels rise, the occurrence of new problems is feared, such as the danger posed by liquefaction. In this study, an analysis was conducted on the changes in the state of groundwater based on future groundwater-use scenarios and forecasts of land subsidence. This involved thinking about the effective use of groundwater to prevent excessive rises in groundwater levels, using a three-dimensional groundwater-flow analysis and a perpendicular one-dimensional subsidence consolidation analysis. As a result, it was shown that it would be beneficial to use groundwater as a means of continuous environmental preservation and as the water resource at the earthquake disaster. At this time new wells were set up at the refuge of the disaster specified in the Nobi Plain. And the remarkable land subsidence was not caused by pumped discharge.

Inspection Data

Unmanned aerial systems (UAS) provide two main functions with regards to bridge inspections: (1) high-quality digital imaging to detect element defects; (2) spatial point cloud data for the reconstruction of 3D asset models. With UAS being a relatively new inspection method, there is little in the way of existing framework for storing, processing and managing the resulting inspection data. This study has proposed a novel methodology for a digital information model covering data acquisition through to a 3D GIS visualisation environment, also capable of integrating within a bridge management system (BMS). Previous efforts focusing on visualisation functionality have focused on BIM and GIS as separate entities, which has a number of problems associated with it. This methodology has a core focus on the integration of BIM and GIS, providing an effective and efficient information model, which provides vital visual context to inspectors and users of the BMS. Three-dimensional GIS visualisation allows the user to navigate through a fully interactive environment, where element level inspection information can be obtained through point-and-click operations on the 3D structural model. Two visualisation environments were created: a web-based GIS application and a desktop solution. Both environments develop a fully interactive, user-friendly model which have fulfilled the aims of coordinating and streamlining the BMS process.

Assembly Constraints

Three-dimensional assembly process planning is a precondition for achieving full product lifecycle management based on three-dimensional modelling. Information expression and management operations of fixture models are key to three-dimensional assembly process planning systems. To reasonably and efficiently achieve the goal of planning assembly processes with a fixture model, the application of a fixture information model to a three-dimensional assembly process planning system is investigated. First, to manage tooling information, a fixture information model is defined that consists of management information, display information, geometric information, assembly constraints and degrees of freedom. Then, based on the analysis of the degrees of freedom of components and the assembly constraint relationship, a method of solving assembly constraints based on degrees of freedom reasoning is proposed. Finally, by using the method of solving assembly positioning based on geometric constraints, the pose transformation and assembly positioning of parts are achieved. Through the development of a tooling function module, the three-dimensional assembly process planning system is improved. The feasibility of the above method is verified using part of a spacecraft as an example.

Hierarchy Process

Reliability of water-sealed conditions is crucial to the safety of water-sealed oil-storage. With a case study of underground water-sealed oil storage cavern in Huizhou, a reliability evaluation index system of water-sealed conditions is estabilished based on the main factors influencing water-sealed conditions. Also, a zonal evaluation of water-sealed conditions of the cave rock mass ranging from 0m to -70m is made by Fuzzy Analytical Hierarchy Process. Moreover, a three-dimensional numerical seepage model is established to study the seepage laws of the groundwater before and after the cavern excavation, and the water inflow during excavation and operation can be forecasted too. The results prove that the cavern site is suitable for the construction of large-scale underground oil storage caverns for its good water-sealed conditions and high reliability.

Abstract During the construction of an airport terminal it was found that as a result of the hydrostatic pressure of underground water the foundation plate of the building had dangerously shifted in the direction opposite to that of the gravitational forces. The only effective measure was to introduce a drainage system on the site. The complex geology of the area indicated that two independent drainage systems, i.e., a horizontal system in the Quaternary beds and a vertical system in the Tertiary water-bearing levels, were necessary. This paper presents numerical FEM calculations of the two drainage systems being part of the airport terminal drainaged esign. The computer simulation which was carried out took into consideration the actual effect of the drainage systems and their impact on the depression cone being formed in the two aquifers.

Product Definition

The manufacturing industry is evolving and starting to use three-dimensional (3D) models as the central knowledge artifact for product data and product definition, or what is known as model-based definition (MBD). The model-based enterprise (MBE) uses MBD as a way to transition away from using traditional paper-based drawings and documentation. As MBD grows in popularity, it is imperative to understand what information is needed in the transition from drawings to models so that the models represent all the relevant information needed for processes to continue efficiently. Finding this information can help to define what data are common amongst different models in different stages of the lifecycle, which could help to establish a common information model. The common information model is a source that contains common information from domain specific elements amongst different aspects of the lifecycle. To help establish this common information model, information about how models are used in the industry within different workflows needs to be understood. To retrieve this information, a survey mechanism was administered to industry professionals from various sectors. Based on the results of the survey a common information model could not be established. However, the results gave great insight that will help in further investigation of the common information model.

Real Objects

Recently, a line of research devoted to the creation of three-dimensional metric simulated models of digital twins has been actively developing. The goal of creating digital twins is to transfer the complicated manufacturing processes, that are performed while monitoring the state of real objects, to a computer environment where a three-dimensional information model was first created. The key requirements are accuracy and efficiency within the conditions of design, construction and operation of real objects when making changes to them. These requirements are met by an active method of the Earth remote sensing, such as laser scanning. Terrestrial laser scanning is used to model objects over a relatively small area and to achieve maximum accuracy. The task of creating digital twin models poses higher requirements for choosing a field stage laser scanning technique and has many features when performing three-dimensional modeling using field data. The article proposes technique of three-dimensional modeling for creating building information models. It analyses the accuracy of the terrestrial laser scanning results. A warehouse space to be reconstructed was selected as the subject of the study. Using the example of laser scanning data for this object, it was indicated that the method under consideration allows ensuring the accuracy of creating a three-dimensional information model up to 1 cm. The laser scanning data of the object show that the considered method ensures 3D information model accuracy up to 1 cm.
