As the population growth and land resources declining, high-rise building project is increasingly common in the construction work. Through in-depth thinking and active exploration, specific attention to matters of deep foundation pit and pile foundation construction technique, which is the key construction techniques in the high-rise building project, was summarized in this article. It suggests to make a careful and detailed geological survey, and then choose the right design program and develop a reliable construction plans. This scheme was proved to be a useful reference and guidance for the development of high-rise building construction technology.

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.

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.

With the scale development of our high-rise buildings, together with the development and enhancing of monitoring technology of deep foundation pit supporting construction. Control accuracy is the main part for monitoring technical process in deep foundation pit supporting construction, the requirement of monitoring is higher and higher than before, relevant monitoring method, frock and tools, earthwork type of shipping and downriver way in engineering construction will develop in revolutionary way. In view of above mentioned, this paper try to do researching on monitoring technical process in deep foundation pit supporting construction in our country, hope to supply reference for counterparts.
