摘要: “两墙合一”地下连续墙作为超深基坑的一种支护方法越来越多的得到广泛应用。当其兼作承重结构时,必须对地下连续墙的竖向承载力值进行预估和计算,目前这方面的理论尚不成熟。以武汉某超深基坑工程为例,结合现场静力载荷试验和后期主体结构沉降监测结果,分析探讨了地下连续墙竖向极限承载力的计算方法,以及计算中尺寸效应系数的选取。其方法可供类似基坑及基础设计参考。

Abstract: The diaphragm wall of "Two walls in one" as a support method for deep foundation pits is increasingly widely used. When it use as supporting structure, its vertical bearing capacity should be predicated and calculated. Taking an excavation in Wuhan project as an example, combining the field monitoring results of static load tests are combined with the post-settlement calculation method of main structures to analyzed the vertical ultimate bearing capacity of the diaphragm wall, and the size effect coefficient is calculated and selected. The proposed method can be used for design of similar excavationsand foundations.
