摘　　要：目前深基坑围护工程广泛采用内支撑结构体系,以保证土方开挖和主体结构的施工安全。一般立柱桩与内支撑施工分属不同作业单位,立柱桩施工的偏差直接影响后续内支撑施工的顺利展开,如何妥善处理立柱桩偏差和保证支撑体系安全为施工期间的重点工作,需要做好相关偏差节点处理和现场签证工作,以保证施工现场施工有序进行以及后期工程结算顺利推进。At present, the deep foundation pit enclosure engineering widely adopts the internal support structure system to ensure the safety of the earth excavation and main structure construction.In general, different operation units are responsible for the construction of post piles and the internal support structure respectively. The deviation of the post pile construction directly affects the successful construction of the subsequent internal support structure. Therefore, it’s key tasks to properly handle the post pile deviation and ensure the safety of the support system during the construction. It’s also needed to do well the relative deviation joint treatment and on-site visa work, so as to ensure the construction can be orderly carried out and the later project settlement can be smoothly advanced.
