摘要
该文依据上海地区砂性土层,围绕土压平衡盾构在砂性土层中进出洞的几种涌砂情况进行分析,并提出针对性的防漏、堵漏等施工技术措施,为盾构施工中类似风险控制起到些许参考作用。
Based on the sandy soil layer in Shanghai,the article analyzes several sand flow conditions when the soil pressure balanced shield goes in and out of cave in the sandy soil layer,and puts forward the construction technical measures especially for the leakages,which can be referred for the similar risk control in the shield construction.
