地铁车站岩质深基坑型钢挡墙结构分析

以重庆某地铁工程为背景,基于岩质基坑支护理论,提出了一种岩质地层深基坑支护结构——型钢挡墙结构。首先对该结构进行理论分析与计算,然后从结构的安全性、工期可行性及经济性等方面进行综合论证,最后通过现场测试验证了该结构的安全性和合理性。型钢挡墙结构丰富了岩质地层基坑支护形式,可为后续类似工程的建设提供借鉴与参考。

Structural Analysis of Section Steel Retaining Wall for Rock Deep Foundation Pit at Metro Station

Taking a metro project in Chongqing City as the background,and based on the rock foundation pit supporting theory,a rock deep foundation pit supporting structure--the section steel retaining wall structure is proposed.Firstly,theoretical analysis and calculation of the structure is conducted;secondly,the structural safety,the feasibility and economy of project construction period are comprehensively demonstrated;finally,the safety and rationality of the structure are verified through field test.The section steel retaining wall structure enriches the foundation pit support for rock texture strata and provides reference for the construction of similar projects in the future.
