A Pile Of Foundation Pit Anchor Bolting And Displacement Analysis In Qingdao

With the rapid development of society, lots of people immigrate into cities. As aresult, urban infrastructure become quite intensive, overground spaces cannot be ableto meet the pace of city development, therefore, people pay more and more attentionto the development and utilization of underground space. So more and more deep andlarge foundation pit appear. the optimization of supporting technology has become animportant research topic in the current construction.In this paper, A case study of Qingdao foundation engineering pile anchor retainingstructure is conducted. By using numerical software and PLAXIS software, thesimulation results of the surface settlement, supporting pile horizontal displacementand vertical displacement analysis of monitoring data is compared with the actualmonitoring data. This results can provide some referential experience for the similarfoundation pit engineering in future.Firstly, the scheme of foundation pit and its advantages and disadvantages isintroduced.Secondly, one part of a foundation pit engineering in Qingdao is taken as theresearch object, then the pile anchor support is determined to used, according togeological conditions and engineering experience. Then the safety and stability of thisanchor section of the foundation pit is checked by using Lizheng foundation software.Once again, the foundation pit monitoring scheme is made. The main content ismonitoring the horizontal displacement of retaining structure, vertical displacement,settlement of surrounding buildings and the axial force of bolt.Finally, the PLAXIS simulation method is expand to the similar fields of engineering,and the method can be used in many engineering problems. This paper takes theQingdao foundation pit engineering as an example, introduces the geotechnicalengineering finite element analysis software, then analyze and calculate thefoundation pit excavation process by using PLAXIS. At last, the simulation numerical result is compared with monitoring data, the feasibility of PLAXIS software infoundation pit excavation is confirmed。...
