摘要
澳门大学新校区专用隧道跨越500m的十字门水道,采用两侧临时围堰形式进行明挖干法施工,围堰稳定性对隧道施工非常关键,文中主要对细砂作为充填砂袋材料的围堰体在加载完成后及堰内抽水后的工况进行稳定性验算分析,为类似工程实施与监控提供数据参考。
The separate tunnel of the new campus of the University of Macao spans the 500m cross gate waterway.Both-side temporary cofferdam is adopted to carry on the constructional methods of open cut and dry application,the stabilization is the main point for the smooth construction of the tunnel.Thus this paper is mainly composed to introduce the stability checking analysis of fine sand-filled sandbag after the loading of the cofferdam and de-watering from the cofferdam,to provide data references for similar project implementation and monitoring.
