摘要
应用受力平衡分析对CFG桩桩间土模量进行了详细推导,同时考虑成桩过程的扰动,提出利用圆孔扩张理论计算扰动区半径,改进和完善了复合土体和桩间土模量的计算方法,有助于提高沉降计算精度。计算表明,该方法在工程上应用较为安全。
The settlement computation is an important content for composite ground design. It is used usually to derive the composite soil modular according to elastic theory & weighting method of the area. The paper has carried on mathematics to derive the soil around the pile modular according to effort balance analysis. The radius of compaction zone[KG1]is derived based on the theory of cavity expansion considering compaction effect. These researches improve and perfect the modular computation method for composite soil and soil around the pile which helps to improve the computation precision. The example results show that the method which the paper set up is safer than the other two methods in practice.
