分层总和法是指将地基沉降计算深度内的土层按土质和应力变化情况划分为若干分层，分别计算各分层的压缩量，然后求其总和得出地基最终沉降量。国家规范计算地基沉降的方法基础都是分层总和法，本法计算的物理概念清楚，计算方法也很容易，易于在工程单位推广应用。
计算方法采用连杆法，地基模型采用规范规定的分层总和法模型。
The hingcd-member method is used in calculation and the model of stratified summation method specified in the Code is adopted as the foundation soil.
地基的沉降变形依据不同地基土的压缩模量，采用分层总和法来确定。
And the foundation settlement is calculated by soil compression modulus, using layer dividing summation method.
对于群桩，将群桩视为实体基础，按分层总和法计算，但未给出相应的限值。
For pile group, the settlement can been calculated by layer and summation mouth by pile group is considered body foundation, but have not given the limits value.
