摘　　要：以北京某超高层建筑物的深基坑支护为例,说明深基坑单支点锚桩在采用等值梁法设计时,随着锚点位置的变化,锚杆的支撑力、桩的最大弯矩也改变了,经过分析研究得出最佳锚点支护位置,使支护系统得到优化,具有较高经济效益,并对该地区类似工程有一定的指导意义和实用价值。The study of the fixedlend single point anchor＇s position, it takes the deep pit support of some extremely high rise building in Peking for example, the paper adopts the equivalent beam method in the single point anchor of the deep pit. Along with the variety of the anchor position, the anchor force and the stake＇s biggest moment change. I have gotten the best anchor position has been analyzed and made the protect system optimum and have better economic performance. So it has certain leading meaning and practical value to similar engineering in that region.

关 键 词：深基坑支护 主动土压力 被动土压力 等值梁法 M法
