| 中文摘要:CFG桩法在高层及多层建筑的地基处理中已有许多成功实例，在变形计算中，《建筑地基处理技术规范》（JGJ 79-2002）推荐使用复合模量法，并提供了计算复合土层压缩模量的应力比法公式。这里通过复合地基载荷试验资料，提出一种改进的面积比法公式。应用该法计算的复合地基沉降值，与建筑物的沉降观测值有较好的吻合度。 |

| Abstract:CFG pile has many successful engineering cases in ground treatment of high buildings. Composite modulus method is recommended by “Technical Code for Ground Treatment of Buildings” JGJ 79-2002 in deformation calculation with stress ratio method formula of composite earth layer compression modulus. In this paper, a modified formula of area ratio method is put forward based on the loading test data of composite foundation. The composite foundation settlement value calculated by this method has a good agreement with the building settlement observation value. |
