摘　　要：结合刚柔组合桩这种新型桩体自身的特点,提出了Boussinesq-Mindlin应力解联合求解法求解复合地基的沉降,详细叙述了关于附加应力参数的求解方法。最后通过现场实例对比表明:联合求解法所求的沉降量比平均附加应力法更接近于实测情况,说明了联合求解法具有一定的适用性。Combined with the new pile＇s own characteristics of mixing pile with stiffness core,getting the method of solving the settlement of composite foundation by Boussinesq-Mindlin united solution.The paper goes into particulars the method of sloving the parameters of additional stress.In the end,through the comparison by examples shows that： Boussinesq-Mindlin united solution comes nearer the truth than average attached stress method.It explains Boussinesq-Mindlin united solution is some certain applicability.
