摘要
福州地铁1号线全线为地下建设,地铁路线主体车站与区间隧道工程均在巨厚淤泥层、富水砂层和花岗岩残积土层等地层中施工,通过研究福州地区特有的工程地质、水文地质等条件综合分析,认为盾构机在软硬不均地层、孤石地层,断裂带、富水砂层中穿越是隧道施工的主要风险源。根据地层的不同工程特性分析了在施工中可能引发的风险事故,同时提出了与之对应的风险措施。
Full line of Fuzhou Metro Line 1is underground construction.The main station of railway line and tunnel engineering construction are in thick mud,water-rich sand and granite residual soil layer.Studying on engineering geological,hydrological and geological conditions of Fuzhou area unique,that shield machine corring in the hard uneven ground,boulder formation,fracture zone and water rich sand layer is the major risk sources of tunnel construction.The author analyzes that they may lead to in the construction of the risk of accidents,and puts forward the corresponding risk response measures.
