摘　　要：在收集近年来有关大直径人工挖孔桩沉降变形计算研究资料的基础上,以成都地区某大学教学楼工程的大直径人工挖孔桩基础为背景,进行了多种方法的计算分析比较,提出了1种可供在成都地区进行卵石地基上人工挖孔桩设计时参考的沉降变形计算方法。Based on the researching datum collected recently, which relate to the calculating methods of settlement deformation of the Large diameter Manpower-excavated arid Cast-in-place Piles（hereafter＇ LMCP＇）, and comparing with a few calculating methods and analysis aimed at the background on the LMCP foundation utilized in one university＇s academic building project in Chengdu area, a new method to calculate the settlement deformation especially for the pebble ground was given in this article as a reference for the LMCP design in Chengdu area.
