基坑支护中水泥土挡墙的水平位移计算

Calculation of the horizontal displacement of the cement-soil retaining wall in foundation pit supporting projects

文章基于在基坑支护工程中,将水泥土搅拌桩生成挡墙围护的工程实际应用,考虑其受力的基本模式和变形的基本条件,简化为弹性支护结构的位移计算模式进行变形分析;并结合文献资料作出对比,同时对支护结构的水平压顶梁进行了简化受力分析对比,得出有益的结论,说明该位移形式符合实际工程。

Based on practical engineering application of making cement and soil mixed piles into retaining wall enclosures, this paper simplifies the retaining wall to be the elastic braced structure considering its basic stress model and deformation condition, and the model of displacement calculation of the elastic braced structure is used to analyze the deformation of the retaining wall. The horizontal top beam of the braced structure is simplified to analyze the forces. A practical application example is presented, and the calculated displacement conforms to the practical situation.
