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.

t is easy to cause the Yangtze River embankment soil of slip even collapse to have a deep foundation pit construction adjacent to the Yangtze River outsideembankment,there are a lot of risk. In this paper, a new combining technique of construction for large caisson is presented. Based on the construction environment, theconstructiontechnology,the smaller earthwork excavation of deep high pressure rotary jet grouting pile with undrained caisson combined construction technology combined with monitoring data for the open caisson excavation control is adopted. It has achieved relatively good results and summarized the advantages of deep high pressure rotary jet grouting pile with undrained caisson combined construction technology in engineering application owing the reference value for engineering applications.

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.

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

It is easy to cause Yangtze River embankment soil slip or even collapse to have a deep foundation pit construction adjacent to Yangtze River outside embankment，with lots of risk . A new combined construction technique for large caisson is presented. The construction technology, the earthwork excavation of deep high pressure jet grouting pile combined with undrained open caisson construction technology, with data monitoring for the open caisson excavation control is adopted. This study mainly summarizes the advantages of deep high pressure jet grouting pile combined with undrained caisson combined construction technology engineering application, and describes the process of the combined construction and measures of deviation correction.The new combining construction technique has made a relatively effective protection for the Yangtze River levee and its ecological environment,having great engineering application value to some similar engineering.
