摘要
本文提供软土层中建筑基坑的带内支撑的围护桩按控制变形设计的简明计算方法 ,其成果与工程实测资料基本相符。对受水平力时的“长桩”和“短桩”的桩身变形提供不同的算法。另对确定坑底软土的“m”值的预设位移和超固结影响也提出了新见解。
The paper gives a simple calculation in the design of retaining pile deformation controlling of internal bracing of foundation pit in soft soil.The calculating result is accord with the information obtained in some engineering.The deformation of long retaining pile and short one under horizontal load can be calculated differently.The opinion is mentioned that displacement and over consolidation effect has influence on the value of “ m ”. \[
