软土地区内撑式挡墙侧向变形经验公式

On empirical formula of lateral deformation of retaining support wall within soft soil areas

针对影响基坑侧向变形的主要因素,通过有限元分析得到深厚软土地区挡墙变形的经验公式,结合工程实际统计数据对比结果,指出该经验公式对软土地区实用程度较高的结论。

In view of main factors influencing lateral deformation of foundation pit, it obtains the enpirical formula of retaining wall in deepthick soft soil area through finite element analysis. Combining with comparison result of actual project statistical data, it points out that： this empirical formula has higher suitable degree in soft soil areas.
