摘要
SMW工法是从日本引进的新型基坑支护施工技术,近年来在国内很多地区得到应用。作者以小规格的型钢-水泥土组合梁模型模拟SMW挡土墙,进行了组合梁抗弯模型试验。凭借试验结果详细分析了组合梁的承载力、组合刚度,推导了组合梁的刚度计算公式。作者对组合梁抗弯模型进行了有限元计算,计算分析值与实测结果的吻合程度较好。
SMW imported is a new construction technology from Japan in the retaining structure of foundation ditch, and it has been applied in many areas of china. The bending tests of small shaped steel and cement-soil composite beam specimens that simulated the SMW retaining wall were done by the author. The load bearing capacity and the composite stiffness of composite beams were analyzed in detail based on the test results. At the same time, the composite stiffness formulas were presented by the author. The finite-element method was applied to analyze the models of composite beams, and the finite-element results were in good agreement with the measured data.
