城建施工复杂工况下的深基坑支护研究

Research on Deep Foundation Pit Support under Complex Conditions of Urban Construction

由于城市中出现很多新的深基坑项目,对周边环境的影响不得不纳入支护结构的考虑范围。文中针对基坑工程开挖深度逐渐增加以及工程周边环境逐渐复杂的特点,总结了现有常用的几种围护结构的支护方式,并且进行了桩锚支护结构的2维数值模拟研究,验证了支护方式的可行性。

Because there are many new deep foundation pit projects in the city, the influence on the surrounding environment has to be included in the consideration of the supporting structure. This paper summarizes the existing supporting methods of several retaining structures, and carries out a 2-dimensional numerical simulation study of pile-anchored support structures to verify the feasibility of supporting methods.
