摘　　要：介绍了一种用管件桩嵌岩的基坑支护技术,其中,上部为传统灌注桩,嵌岩部分采用管件桩,管件材料为钢管。通过工程实例,采用敏感性分析方法,计算和分析了这种基坑支护结构的内力和位移对有关土工参数的敏感程度,结果与传统的灌注桩支护结构的土工参数敏感性一致,证明了该技术的实效性。This paper is about a patented technology of foundation pit support with tubular piles embedded rock. The upper part is a traditional cast-in-place pile,and the rock-embedded part adopts pipe piles which are steel pipe. Through engineering examples,using sensitivity analysis method to calculate and analyze the sensitivity relevant geotechnical parameters of foundation pit supporting structure internal force and displacement. The sensitivity results are consistent with the the traditional cast-in-place pile support structure. This patented technology is practical.
