| 摘 要： | 柔性基础下复合地基的沉降计算一直较难确定.利用Mindlin解与Boussinesq解联合求解柔性基础下复合地基的附加应力,并利用Vesic小孔扩张理论计算桩体刺入柔性基础的量,后对分层总和法求得的沉降进行修正,可以得到与实测接近的沉降计算值.

| Abstract: | The stress distributions in soil under composite foundation with soft base slab and stiff base slab are very different. The methods of stress and settlement used frequently are based on the foundation with slab. The results of these methods are not fit with the actual. Using Mindlin solution and Boussinesq solution, the additional stress and settlement are acquired and using Vesic theory, the earth arc effect on pile top are acquired. Then, compared with the results of layerwise summation method, the stress and settlement can be got with good agreement to practice test. |
