复合地基桩基础新技术

INTRODUCTION OF NEW PILE FOUNDATION TECHNIQUE FOR COMPOSITE FOUNDATION

对比在软土地基中密集设计桩基础的方法,介绍了在桥梁桩头周边兼用复合地基地基加固的新技术,并从地基桩基础的有效性、复合地基桩基础设计方法、还待解决问题以及模型试验介绍了该技术,并对其抗震性能作出了评价。

Compared with dense file foundation design method for soft foundation, this paper introduced a new reinforcement technique using composite foundation around the pile head of bridge and described the new technique on the aspects of validity of pile foundation, composite pile foundation design method, existing problems and model tests, etc. The aseismic performance of the new technique was also evaluated.
