摘要
刚性桩复合地基是靠桩端阻力和摩阻力共同作用,以摩阻力为主属于磨擦桩,上部载荷由桩和被改良的天然地基土体共同承担。通过工程实例说明在岩溶地区大载荷作用下利用刚性桩复合地基代替桩基既安全可靠又经济,值得推广应用。
The paper presents a case history of using rigid column composite soil as a soil improvement method for the foundation construction of a cement storage facility in karst terrain. The results indicate that this method is technically reliable and cost effective method.
