Study On The Difference Of Supporting Support And Pile - Anchor Support In Foundation Pit

With Urban land problem is becoming more and more serious with the rapid development of China’s economy and the city size getting bigger, in order to solve this difficult problem, projects like high-rise buildings, underground·engineering, municipal engineering and underground space development appeared in large numbers. Judging from recent years, foundation pit engineering get rapid development, and research in this field gradually become an important subject in geotechnical engineering. Inner Brace structure and anchor piles supporting structure are current excavation wider use two supporting structures. Both support the same effect in supporting research projects have been less bad situation. This paper, taking a foundation pit engineering in Kun Ming as the research background, Use MIDAS/ GTS numerical software during excavation under two supporting structures to carry out excavation, and analyzing the simulation results obtained in both cases, and compared. It is to study the effect of supporting the best indicator of the quality of the horizontal displacement of the supporting piles, surface subsidence, uplift Bottom situation. The main contents are as follows: This article elaborated and summarized the Present situation of deep foundation pit in our country and the application of numerical simulation method on it, then introduced the research contents and methods of this subject:In the background of a deep foundation pit in Kunming, the author used the numerical simulation software MIDAS/GTS built models and analysis two kinds of excavation processes in different supporting structure. Analysis and summary The horizontal displacement of the retaining pile, ground settlement and Changes of basal heave in the digging of the excavation under two kinds of support structure system Contrast The horizontal displacement of the retaining pile, ground settlement and Changes of basal heave under two kinds of support structure system.. Prove in this excavation engineering, For the supporting effect Internal bracing system better than anchor pile support system...
