摘　　要：在地质工程勘查中，排桩支护结构，采用挖孔灌注桩及相应配套技术，已发展成为对基坑变形有严格控制要求的深基坑开挖支护结构的一项重要手段。本文结合施工实践，论述了排桩桩型结构设计、配套技术的发展，及施工技术与质量控制等问题。In engineering geological investigation, the multi－pile sheathing structure, which employs digging cast－in－place pile and the corresponding supporting technique, has now become an important means of sheathing structure in the excavation of deep foundation pit whose deformation should be strictly controlled． Based on construction experience, this paper deals with the development of the design of multi－pile structure, the development of the corresponding supporting technique, the construction technique, the quality－control and other relevant problems．
