摘　　要：在两个模型的基础上,针对水泥搅拌桩加固高速公路可能出现的浮桩情况研究了地基总沉降和未打穿土层厚度的关系;针对可能出现的薄硬夹层情况探讨了地基总沉降和中间薄硬夹层厚度的关系,并因此得出了一些对工程有益的结论。Based on two models, aiming at the case of floating piles in strengthening weak fotmdation of expressway with cement mixing piles,the relation between total foundation settlement and height of partially penetrated layer soil is worked out, and then aiming at the case of thin hardpan layer, the relation between total foundation settlement and height of thin hardpan layer is found out. As a result, some instructive conclusion is deduced.
