摘　　要：深圳地铁5号线地质复杂,地层变化大,大量存在上软下硬地层,对连续墙施工工期有很大影响。大学城站局部进入微风化花岗岩,施工进度缓慢,难以满足工期要求。从实际出发,为确保工期、安全、质量等要求,在连续墙围护结构中局部使用吊脚连续墙。从方案、计算、吊脚墙施工技术、锚索施工技术进行详细介绍。Line 5 of Shenzhen metro features complex geology, great variations in ground and a lot of mixed upper soft rocks and bottom hard rocks, causing trouble for the construction of diaphragm wails. At Daxuecheng station, weak-weathered granites were encountered which slowed down the construction progress and the project schedule was difficult to satisfy. In order to ensure the project schedule, requirements for safety and quality, considering the practical situation, partial diaphragms, i. e. , diaphragm walls without footings, were adopted at some places. The paper describes in detail the scheme, computation, partial wall fabrication and anchor cable technique.
