宏远大道站基坑围护结构稳定性分析
摘要
随着改革开放这些年来，我国综合经济实力得到显著提高，城市化建设速度也飞快提升者，大量的劳动人口涌入造成城市中的交通压力也面临着严峻挑战，单一的路面公交出行已经无法满足日益增长的居民出行交通运输的要求，于是地铁这种具有承载量大，速度快等优势的出行工具正在逐渐成为城市百姓出行的不二之选。基坑的安全可靠直接关联着地铁站的工程安全，而如今基坑工程周边坏境的复杂性，无疑不在驱使我国要从过去单单的基坑支护结构本身的安全强度稳定转向要求更高的基坑变形控制。变形与稳定性是息息相关的，这也目前岩土工程界的重要研究课题之一。本文对基坑围护结构稳定性影响分析问题进行了综述。

Abstract
Over the years with the reform and open policy, our comprehensive economic strength increased significantlyurbanization also fast ascending speed, a large number of labor force poured into the city#39;s traffic pressure is faced with severe challenges, a single road public transit trip transportation has been unable to meet the growing demands, so the subway this has big capacity, fast speed of travel tools are gradually become city people travel of choice.The safety and reliability of the foundation pit is directly related to the engineering safety of the subway station. However, the complexity of the surrounding environment of the foundation pit engineering today undoubtedly does not drive our country to change from the safety and stability of the foundation pit supporting structureitself to the higher foundation pit deformation control.Deformation and stability are closely related, which is one of the important research topics in geotechnical engineering field.In this paper, the influence analysis of foundation pit enclosure structure stability is summarized.
Key words: foundation pit retaining structure; Stability; Deformation; impact
引言
拿我们现在身处的时代与之前的时代相对比，我们会发现不管从哪个方面来看来比较，我们的周围乃至整个社会、世界都在发生了巨大变化，特别是在工程建设发展的来说，那简直是天翻地覆。如果说十九世纪是桥梁、铁路的时代，那么当今毫无疑问就是地下工程的时代[1][2]，地下工程建设得到巨大发展。而且特别在我国这几十年来，城市建设迅猛发展，地面高楼耸立、地面上空高架桥密密麻麻，城市的三维空间[3]也基本被完全开发利用，地表上可利用空间已经严重不足。因此，开发利用地下空间已经是当今或着未来主要的方向之一。比如在面临现在越来越沉重的交通运输压力的时候，发展地下交通工程，是能很有效解决交通运输问题的。
