| 摘 要： | 某地下开挖工程出现透水事故,引发地基沉陷,上部建筑物楼体开裂。地下沉陷情况不明,对周边建筑安全构成威胁。采用地震映像技术对隐患区地下土层变化进行了追踪测试。结果表明:地下土层受透水影响,出现多点沉降异常,且伴有地下空洞正在形成。数据分析结果为沉降区后期加固修护提供了依据,并可为类似工程处理提供参考。

| Abstract: | In the water accident of an underground project,the foundation settlement and the cracks of adjacent structures are caused.Safty of surrounding buildings is threatened because of unknown subsidence.The technology of seismic image is applied to tracing test of underground soil in hidden trouble area.The results show that,underground soil layers are affected by water accident,by which multi-point abnormal subsidence and underground cavities are caused.This conclusion is valuable in post repairing and strengthening in hidden trouble area. |
