水工建筑物复合地基竖向增强体的存在使得复合地基压缩模量（即复合模量）的测试和计算变得更为复杂，传统的方法针对不同形式的复合地基给出了不同的近似公式。从理论和实践两方面，对复合地基压缩模量计算方法进行分析，研究探讨了一种新的计算公式，结果表明：按新的计算公式得出来的压缩模量比旧公式更接近计算值，说明新的计算公式更合理一些；旧公式中压缩模量的计算忽略了非挤密增强体的挤密作用，以及增强体和土体承载力发挥不协调等因素，压缩模量的计算不严密。

The hydraulic structures of composite foundation because the existence of the vertical compression modulus of composite foundation (that is,the composite modulus)of test and calculation become more complex,the traditional way is to different forms of composite foundation is given different approximation formula. From the two aspects of theory and practice,the calculation method of composite modulus of composite foundation was analyzed and the research to explore a new formula for calculating. The results show that the new formula to calculate out the compression mod-ulus is more close to the calculated value than that of the old formula,showing the new formula is more reasonable;old formula of compression mod-ulus calculation ignored the enhancement body compaction effect,and reinforcement and discordant factors such as soil bearing capacity,the calcu-lation of compression modulus is not right.
