摘　　要：针对某旧区基坑工程导致相邻住宅楼墙体开裂情况,根据工程地质条件、水文地质、现场观测结果和理论分析,找到了发生事故的原因是因基坑支护形式选择不当、地面防渗水能力不强、施工质量欠佳及预警不力等引起的,制定了防水处理、支护处理等措施,取得了良好的效果,为类似工程提供借鉴.In connection with the geological and hydrological conditions, the site testing rezults and the theoretical analysis of the wall cracking of an old adjacent building, the paper has found its causes to be inappropriate choice of the foundation pit shoring, lack of impermeability of the ground, bad construction quality and lack of early warning. Furthermore, the paper proposes some water-proof and shoring countermeasures whose practice has obtained good results, thus providing references for similar projects.
