摘要
复合地基的沉降计算是一个重要的岩土工程问题.由于粉喷桩等柔性桩在桩与土之间具有过渡带,所以利用面积加权平均法对加固区常用的复合模量公式进行了修正.通过与实际工程进行对比,利用修正后的公式计算的沉降值比以前的公式计算结果更接近实测值.
Settlement calculation of composite foundation is an important geotechnical engineering problem. According to the actual behavior of flexible pile, the transition zone is established between the pile and soil. On this basis, the composite modulus formula is improved by means of the weight average method. Comparing with actual engineering, the settlement value calculated by the improved formula is more accurate than by previous area formula.
