摘　　要：近年来我国经济发展迅猛,基础建设规模逐渐扩大,为满足建筑设计的要求,桩基础应用愈加广泛,各种新型桩型层出不穷,载体桩就是最新发展起来的一种新型桩。载体桩由于采用建筑垃圾等当做填充料,用细长夯锤对填料进行夯击密实,在桩头形成载体,能大幅提高承载力,而且能够消融建筑废料,节约成本,是一种性价比极高的桩型,符合可持续发展的需要。本文结合都江堰地下工程和隧道防火保护实验室载体桩典型工程,采用现场测试、数值模拟等方法,对载体桩的承载性能和工程应用进行了试验和理论研究。In recent years, with the rapid growth of china＂ s economic, the infrastructure has been widely expanded to meet the requirements of the building design. Pile foundation has been more widely used than before. Various kinds of new forms of piles turn up. Ram-compacted pile with bearing base is one of them, it uses construction waste as the filling material and use hammer long and thin to pound the filling material compacted so as to form a bearing base at the bottom of the pile. It can not only significantly improve the resistant stress, but also dissolve the construction waste and save costs. Ram-compacted pile with can satisfy the need of sustainable development. The paper protection laboratory in Dujiangyan the application of ram-compacted numerical simulation. bearing base is a pile with high cost-effective which takes the underground engineering and tunnel fire as a typical construction. A systemic study on the resistant stress properties and pile with bearing base is executed through field test, theoretical analysis, and
