| 摘 要： | 临海抛石回填和海沙冲填复杂地层，具有高透水性的特点，尤其受潮汐影响地下水位变幅明显。青岛奥运会国际帆船中心地下车库工程，采用放坡开挖，坡面挂网喷射混凝土保护，高压旋喷注浆穿透抛石层形成止水帷幕等技术措施．有效地解决了4．5m高潮汐落差情况下的基坑止水问题。

| Abstract: | The riprap and sand backfilled stratum on sea beach has high water-permeability. In particular, tide affects the underground water level obviously. In the Underground Parking Project of Qingdao International Sailing Center of the Olympic Games, some technical measures were taken that effectively solved the water stop of the pit under tide head of 4.5m, including sloping excavation, mesh and shotcrete on the slope, pressurespraying mortar into riprap layer to form water-stop curtain and etc. |
