| 摘 要： | 为了确定CFG桩复合地基反力系数,分别采用设计软件计算法、载荷实验法、沉降监测反演法和数值分析法等,针对具体工程案例分别确定其复合地基反力系数,并将各种方法的计算结果进行了比较,发现由设计软件和数值分析方法计算所得的复合地基反力系数偏小,单桩复合地基载荷实验和沉降监测反演法确定的地基反力系数值较为接近.

| Abstract: | To determine the reaction coefficient of CFG composite foundation,PKPM software method,load test method,back analysis based on settlement monitoring and numerical simulation method are used to obtain composite foundation reaction coefficient of a case project,and the results of various methods are compared.The composite foundation coefficient determined by PKPM software and numerical simulation are too small,and those derived from single pile composite foundation loading test and back analysis based on sett... |
