近十多年来,我国高层建筑发展很快,地下空间得到充分利用,促进了深基础的发展,随之产生了深基坑支护设计与施工问题。深基坑工程涉及岩土力学、结构力学、材料力学、地质水文科学、环境保护等学科,影响因素众多。同时,深基坑开挖施工对整个工程及其周围环境影响重大。本文对深基坑支护的设计及施工中一系列的问题进行分析,探讨。
In recent ten years, the rapid development of high-rise buildings in our country has taken full advantage of the underground space and promoted the development of deep foundations. As a result, the design and construction of deep foundation pit support have arisen. Deep foundation pit engineering involves geomechanics, structural mechanics, material mechanics, geology and hydrology, environmental protection and other disciplines, many influencing factors. Meanwhile, the excavation of deep foundation pit has a significant impact on the whole project and its surrounding environment. In this paper, a series of problems in the design and construction of deep foundation pit support are analyzed and discussed.
