摘要
根据软土地区带支撑深基坑周围地表沉降特点,提出预测函数模型,利用工程实测资料和有限元分析讨论参数与土体性质、开挖深度等因素的关系,确定参数的取值方法。最后利用工程实例进行验证,其结果具有一定的工程借鉴意义。
Forecast＇s function model is given according to surface subsidence caused by deep foundation engineering in soft soil area. Project data and finite element method was used to study relations between function parameters and soil features, and depth of excavation. Form the result selection method of function parameters was given. Finally, the function was tested by projects data, and comparatively consistent, which could provide some reference for other similar projects.
