摘要： 以紧邻建筑物管桩基础的深基坑支护设计和施工为例，综合考虑周边环境和水文地质条件等因素，选取了钻孔灌注桩作为挡土结构、旋喷桩止水、坑内预应力内支撑的支护方案。通过对设计与施工中遇到的问题进行分析与解决，得出了一些相关结论，可为类似的基坑工程的支护提供参考。

Abstract: Based on the deep foundation pit design and construction adjacent the pipe pile foundation, the surrounding environment, hydro\|geological conditions and other factors were comprehensively considered, the cast\|in\|situ bored pile was as the retaining structures, the rotary jet grouting pile was as the water resistant curtain and the prestressed internal support was in the foundation pit. There were some problems encountered during the design and construction, which were solved by analysis and some relevant experience were obtained, which provides reference for similar projects to provide experience in supporting.

Key words: deep foundation pit, pipe pile foundation, rotary jet grouting pile, prestress, internal support
