摘要
以武汉白沙洲大道路面塌陷事故为背景,针对该工程场地特殊的工程地质条件,分析了由于地下排水管线及其施工工艺所引发的工程灾害问题,提出采用SMW工法作为修复对策对破损管线进行明挖施工,结合施工反馈给出了SMW工法在粉砂等类似地层中的施工经验参数。
This case study presents a sudden ground collapse at Baishazhou Boulevard in Wuhan city and its emergency remedia- tion. The conventional approaches of underground drainage pipe construction techniques and their induced engineering hazards are also discussed. It is concluded that the Soil-Mixing-Wall （SMW） method has an advantage for the open excavation support in the emergency remediation. The SMW construction parameters in the silty soils fed back from the construction observation are also summarized in the paper.
