摘要
引用考虑群桩中桩与桩之间“加筋效应”的剪切变形传递法计算了桩身的压缩变形,采用等代墩基分层总和法计算了群桩基础下卧土层的压缩变形,以此来确定群桩基础的最终沉降量。详细地讨论了用于确定群桩基础最终沉降量的土的压缩模量的选取方法,结合实例验证了混合法在工程上的可行性。
By considering‘the effect of bar’between piles,the formula for calculating the pile deformation is used in this paper.The settlement of pile-group foundation is calculated with the equivalent pier method.The method for determining the compression modulus of soils for final settlement is discussed.An engineering example proves the feasibility of the mixed method.
