摘　　要：北京庄胜商业中心基坑最深１４．８ｍ，针对现场环境复杂、土质差和地下水等条件，确定采用锚钉墙支护方案。本文介绍该方案的边坡坡度设计、锚体长度、直径计算、锚体抗拔试验、锚钉墙的施工和位移监测。最后总结了锚钉墙支护的特点，并对一些问题进行了讨论。The construction of a 14. 8m deep foundation of the Beijing Zhuangsheng Shopping Centre project had been found with various complicated difficulties such as the poor soil bearing capacity and troublesome underground water treatment. After due consideration, an application of the anchor strut technology for shoring of deep trench foundation method, ASTSDTFM, was eventually adopted and proved successful. In this article, a large number of technical problems, namely: the design of trench slope, the calculation of anchor strut's length and diameter, the extraction test of anchor strut, the construction and surveillance of ASTSDTFM have been comprehensively introduced. In conclusion, it has summed up the specific features of ASTSDTFM and put forward some helpful suggestions about the application of ASTSDTFM.
