摘　　要：高压旋喷劲芯桩复合地基由于在高压旋喷桩的桩身内部插入刚性加固件,提高了桩身的刚度和承载能力,从而整体提高了地基的承载能力,使地基不容易出现变形,能够满足较大的承载力要求,增强了其适应性。本文通过工程实例详细介绍了高压旋喷劲芯桩复合地基的工作原理、设计及其施工工艺,以期为类似的工程设计提供借鉴。Due to the insertion of rigid firmware inside the pile of high-pressure rotary spray pile,the stiffness and carrying capacity of the pile is improved by rigid firmware,thus improving the carrying capacity of the high-pressure rotary spray pile composite foundation as stable as a whole and less prone to deformation,so as to enhance its adaptability tomeet the larger load-bearing requirements.In this paper,the working principle,design and construction process of the composite foundation of the high-pressure rotary-jet core pile are introduced in detail through engineering examples,which can provide reference for similar engineering design in the future.
