Design And Construction

The rapid development of deep foundation pit engineering, has become an important part of the urbanization construction, which brings deep excavation support of geotechnical engineering problem research also became a major issue. This paper uses the international well-known geotechnical engineering numerical simulation software FLAC3D, through 3D finite difference numerical calculation and analysis, to better simulation calculation and analysis of deep foundation pit construction site condition, forecast after excavation of the deep foundation pit deformation displacement and dangerous position, analysis of deep foundation pit excavation process isolation pile - steel shotcrete combined support effect. Three dimensional numerical model analysis and calculation in deep foundation pit engineering design and construction scheme optimization with economy is convenient wait for a obvious advantages, can for deep foundation pit excavation of deep foundation pit support design and construction to provide effective basis.

Combined with a specific foreign-related project and based on the detailed report of the engineering geological investigation, this paper describes the application of the selected support structures of shotcrete-bolt and bored piles with high pressure rotary jet grouting waterproof curtain from aspects of scheme optimizing, design and construction, underground watertable lowering and result monitoring. Satisfactory achievements have been made in cost saving, shortening duration, facilitating construction and environmental protection etc. It demonstrates that two or multiple support systems can be used simultaneously in one foundation pit as support structure.

This paper takes example of a foundation pit in Haikou, analyzing the influence on the surrounding buildings in the course of the excavation depth, daily rainfall, foundation form of the building and other factors. The results show that the excavation depth and strong rainfall may lead large deformation of the surrounding buildings, and the deep foundation pit has obvious effect on surrounding building with shallow foundation. Therefore, those factors should be considered adequately in the design and construction of deep foundation pit

Taking the J2 area YK10+615~YK10+650 miles section related to the connection line of River-crossing tunnel to Nanjing plum delta--the youth Olympic axis underground traffic system engineering as the background, the 3d model is established by using finite element software MIDAS/GTS, the mileage period of excavation process is simulated, discuss the influence of excavation on adjacent soils. Calculation results show that the excavation will inevitably cause deformation of adjacent soil, and comparing the results of calculate and the actual monitoring data show that the method has certain guiding significance to actual engineering.
