| 中文摘要: |
| 针对半刚性复合地基中广泛使用的水泥土桩和CFG桩在工程实践中和研究中的一些问题，例如水泥土桩的变形模量、水泥土桩及CFG桩的桩间土应力发挥系数β、水泥土桩及CFG桩的复合地基静荷载试验方法等。结合一些具体工程，对这些问题进行了试验研究及理论分析；提出了水泥土桩的变形模量和桩间土应力发挥系数的建议取值以及解决垫层设置和垫层压缩量对工程实践影响的修正方法。 |
| 英文摘要: |
| The authors studied some problems in a composite foundation, such as the deformation modulus of cement pile, the coefficients of stress development of soil of cement pile and CFG pile. Experiments with the static loading testing method and theoretical discussion were made for some projects. Practical values of the deformation modulus of cement pile and coefficients of stress development of soil of cement pile and CFG pile were proposed. A practical method of modifying the effect of pillow setting and pillow compression problems in designing and constructing the composite foundation was also presented. |
