小直径圆形地下连续墙围护结构入土系数分析

Analysis on Driven Coefficient of Minor Rounded Continuous Concrete Wall Structure

宝钢浦钢搬迁工程中某地下漩流沉淀池工程,拟采用圆形地下连续墙作围护结构;在搜集了江浙地区其它类似工程的资料以及离心模型试验结果的基础上,从基坑规模和地下水条件2个方面对该小直径圆形地下连续墙的入土系数进行了讨论,为今后该类工程入土系数的合理取值提出了建议。

In Baosteel PuDong Steel Works relocation project, rounded continuous concrete wall are used as toeboard structural in underground rotation flaw pool item. This paper researches similar projects data in JiangSu ＆ ZheJiang province, and put to centrifugal modal test. Based on the two results, this paper discusses the driven coefficient of minor rounded continuous con- crete wall in foundation scale and groundwater condition two ways. And then give advise about how to fix data of driven coefficient to the future similar project.
