摘　　要：某轨道交通1、2号线联络通道暗挖隧道近距离穿越游泳池和周边建筑物,为确保该暗挖隧道实现无水施工,通过对“WSS深孔注浆”和“双排超前小导管配合全断面注浆”两种防水加固方案从成本、工期、技术优势等方面进行对比分析,最终选择后一种方案;通过监控量测,证明所采用的施工方案防水加固效果好、进度快、成本低、便于施工。The underground tunnel of the connecting passage of some rail transit line 1 and line 2 passes through the swimming pool and surrounding buildings in a short distance.In order to ensure water-free construction for the underground tunnel,two waterproofing reinforcement schemes:“WSS deep hole grouting”and“double rows of advanced small conduits with full section grouting”are compared in terms of cost,construction period and technical advantages,and finally the latter scheme is selected.Through monitoring and measurement,it is proved that the adopted construction scheme is featured with good waterproofing reinforcement effect,fast progress,low cost and convenient construction.
