摘要
以复合地基和不同刚度类型桩复合地基理论为前提,介绍了长短桩复合地基。讨论了褥垫层在长短桩复合地基中的作用,得出在刚性桩及半刚性桩共同作用的复合地基工程中,需要设置褥垫层来保证桩、土共同作用;比较分析了在工程中常用的几种计算长短桩复合地基承载力和沉降的方法。
The paper introduces the application of the long- short- pile composite foundation on premise of such theories as composite foundation and pile composite foundations with different rigidity,discusses functions of cushion layer in the long- short- pile composite foundation,and produces the idea of needing cushion layer to assure the joint function of pile and earth in rigid- pile and the semi- rigid- pile composite foundations.It also compares and analyzes some common approaches to calculating the bearing capacity of foundation and composite foundation settlement.
