Mountain Disasters

Climate change increases the frequency of localized heavy rains and typhoons. As a result, mountain disasters, such as landslides and earthworks, continue to occur, causing damage to roads and residential areas downstream. Moreover, large-scale civil engineering works, including dam construction, cause rapid changes in the terrain, which harm the stability of residential areas. Disasters, such as landslides and earthenware, occur extensively, and there are limitations in the field of investigation; thus, there are many studies being conducted to model terrain geometrically and to observe changes in terrain according to external factors. However, conventional topography methods are expressed in a way that can only be interpreted by people with specialized knowledge. Therefore, there is a lack of consideration for three-dimensional visualization that helps non-experts understand. We need a way to express changes in terrain in real time and to make it intuitive for non-experts to understand. In conventional height-based terrain modeling and simulation, there is a problem in which some of the sampled data are irregularly distorted and do not show the exact terrain shape. The proposed method utilizes a hierarchical vertex cohesion map to correct inaccurately modeled terrain caused by uniform height sampling, and to compensate for geometric errors using Hausdorff distances, while not considering only the elevation difference of the terrain. The mesh reconstruction, which triangulates the three-vertex placed at each location and makes it the smallest unit of 3D model data, can be done at high speed on graphics processing units (GPUs). Our experiments confirm that it is possible to express changes in terrain accurately and quickly compared with existing methods. These functions can improve the sustainability of residential spaces by predicting the damage caused by mountainous disasters or civil engineering works around the city and make it easy for non-experts to understand.

Agustín de Betancourt y Molina was one of the most distinguished engineers of the eighteenth and nineteenth centuries with numerous contributions to various fields of engineering, including civil engineering. This research shows the process followed in the documentation of the cultural heritage of that Canary engineer, especially in the geometric documentation of a machine for cutting grass in waterways presented in England in 1795 after three years researching on theory of machines. The baseline information has been recovered from the Canary Orotava Foundation of History of Science who has spent years collecting information about the Project Betancourt, in particular, planimetric information as well as a small report on its operation and description of parts of machine. From this information, we have constructed a three dimensional (3D) model using CAD techniques with the use of Solid Edge ST7 parametric software, which has enabled the team to create the 3D model as well as different detail plans and exploded views.

Abstract: Research methodology is a method to consistently resolve the research problem. Research methodology may be termed as knowledge of science for studying how research is done empirically and theoretically. In this paper we have studied different steps that are usually taken by a researcher in studying his research problem of civil engineering along with the logic behind them. It is utmost important for the researcher to have the knowledge of the research techniques/method along with its methodology. Researchers also need to understand the presumptions underlying various techniques and they need to know the criteria by which they can decide that certain techniques and procedures will be applicable to certain problems and others will not. All this means that it is necessary for the researcher to design his methodology for his problem as the same may differ from problem to problem. Research methodologies are the need of hour due to modernization in research field of civil engineering. Nowadays only innovative research methods are adopted in branch of civil engineering like geotechnical engineering, geoenvironmental engineering, structural engineering, geo-mechanics etc so that best results are obtained from these methodologies. In this paper we are going to discuss role of some of the research methodologies used for research purposes in geotechnical engineering for respective research problems.

Result Analysis

In the traditional civil engineering industry, only abstract theoretical concepts are applied to express complex realistic contents, but this method of information transmission is sometimes very limited for engineering participants, because its expression is not comprehensive and specific and also makes the recipients have difficulty in understanding its information. The rise and development of virtual reality (VR) technology has become a good assistant to overcome this difficulty, providing an extremely effective means for displaying and simulating civil engineering project in real time. This paper introduced the methods and principles of VR platform system and structure dynamic analysis, conducted virtual scene design and three-dimensional modeling of civil engineering project, analyzed the synthetic debugging and simulation roaming of the virtual environment, proposed the engineering model of virtual construction process and planning structure calculation, discussed the realization method of virtual project management and visualization, and finally performed the simulation and its result analysis of panoramic display and planning of civil engineering project based on VR technology. The results show that the VR technology can simulate various environments and activities of civil engineering projects in advance, analyze the rationality of various schemes, and modify their different functional parameters, so it can achieve the simulation optimization of project planning, design, and construction.

Reinforced soil has been among the most effective soil modification materials. Its use has been expanded rapidly into civil engineering, geotechnical engineering and pavement engineering. Reinforcing subgarde in pavement systems has always been an issue. This study focuses on effect of fiber inclusion on the strength of subgrade material. Plastic fiber was used for this investigation. Fiber contents and aspect ratio have been changed during these tests. The fiber percentage varied from 0 % (for unreinforced samples) to 2%. Clay was used as sub grade material. Unconfined compression tests were carried out to investigate behaviour of the composite under different condition. The fiber length and fiber content found to play important rule on the strength of composite. Furthermore it was observed that ductility of sample increased by fiber inclusion.
