深基坑支护结构设计与施工质量控制研究

Research on Design and Construction Quality Control of Deep Excavation Support Structure

在社会经济不断发展背景下,轨道交通工程项目也日渐增多。深基坑支护作为轨道交通基础工程的重要构成部分,其施工好坏会直接影响到轨道交通运行的稳定与安全。因此,需要结合实际对深基坑支护结构进行科学设计,对于整个支护施工过程也要实施严格控制,避免发生质量问题。围绕深基坑支护结构设计的主要内容,对深基坑支护施工需要注意的要点进行详细阐述。以实际工程案例为例,从前期工程勘查分析、确定支护结构形式、组织开展施工作业、强化支护施工管理等方面入手,详尽探讨深基坑支护结构设计与施工过程,以及取得的效果,为类似工程作业提供借鉴。

Against the backdrop of continuous socio-economic development,the number of rail transit engineering projects is also increasing.Deep foundation pit support,as an important component of rail transit foundation engineering,its construction quality will directly affect the stability and safety of rail transit operation.Therefore,it is necessary to scientifically design the deep foundation pit support structure in combination with reality,and strictly control the entire support construction process to avoid quality problems.Elaborate on the main content of deep foundation pit support structure design and the key points that need to be paid attention to in deep foundation pit support construction.Taking practical engineering cases as an example,starting from early engineering exploration and analysis,determining the form of support structures,organizing construction operations,strengthening support construction management,etc.,this paper explores in detail the design and construction process of deep foundation pit support structures,as well as the results achieved,providing reference for similar engineering projects.
