摘　　要：根据地质条件,大面采用上部土钉墙+下部桩锚联合的基坑支护结构形式,护坡桩间设高压旋喷形成止水帷幕体系。基坑施工过程中,对支护结构水平位移、沉降、地下水位、锚杆拉力等进行监测。现场监测表明:围护结构和周边环境的变形均在允许范围内,效果良好。According to geological conditions,soil nailing walls compounding with pile and anchors are designed as supporting structure,and high-pressure jet grouting technology is adopted among the supporting piles to form waterproof curtain.During construction,some control parameters are monitored,including the horizontal displacement,settlement,groundwater level and anchor stress.The monitoring results show that the displacement can meet the requirements,and the effect is good.
