摘要:
 分析型钢水泥土搅拌墙(桩)复合结构的作用机理可知:在一定荷载荷载作用下,型钢水泥土搅拌墙(桩)复合结构刚度为型钢和水泥土刚度之和。型钢水泥土的抗弯试验结果表明:水泥土对复合结构的刚度贡献达到20%以上,并给出相应的计算方法;利用抗剪强度标准值和28 d无侧限抗压强度值的相对数值关系再次证明水泥土的刚度贡献不可忽略。以武汉琴台美术馆基坑工程为依托,采取“双排桩内插H型钢”支护方式,分别对型钢及型钢水泥土搅拌墙(桩)承载力进行了计算,并对支护结构稳定性进行验算,辅以天汉软件进行复核验算,均满足规范要求。
Abstract:
 According to the analysis of the function mechanism of the composite structure of steel cement-soil wall, the stiffness of shaped steel and cement-soil wall is the sum of shaped steel’s and cement-soil’s. The bending test of the shaped steel cement-soil wall reveals that the stiffness contribution of the cement soil to the composite structure reached to 20% and over. Moreover, the result of the relationship between the standard value of shear strength and the value of 28d unconfined compressive strength shows the contribution of cement-soil cannot be neglected. This essay is based on foundation pit support of Qintai Art Museum. The foundation retaining scheme is “double row piles inserted with H shaped steel.”The bearing capacity and the stability of the retaining structure are calculated respectively, and the calculation with Tianhan software is checked. All the results meet the specification requirements.
