摘　　要：地铁车站深基坑施工是一项复杂的系统工程,投资大、技术复杂,由此引发的重大灾害事故报道屡见不鲜。以实际的基坑工程为背景,研究深基坑支护选型和含锚杆粉砂性地层地下连续墙的施工质量控制方法。采用改造后的成槽机抓斗,清除既有锚杆,保证地下连续墙成槽施工质量和工期。地下连续墙采用改进后的清障技术,有效减少墙面鼓包,成槽基本无塌孔现象。The construction of deep foundation pit of subway station is a complicated system project, which has large investment and complicated technology. On the background of actual foundation pit engineering, the selection of deep foundation pit support and the construction quality control method of underground diaphragm wall with silty rock bolt are studied. A modified trenching machine grab was used to remove the existing anchors and to ensure the quality and duration of the trenching of the underground diaphragm wall. The underground diaphragm wall uses an improved clearing technique to effectively reduce wall bulging and the formation of the trench is basically free of collapsed holes.
