摘要
结合苏州市轨道交通一号线临顿路～仓街站区间盾构工程实例,探明苏州粉质黏土及粉砂地层盾构正常掘进引起的隆起和沉降变形特征;研究盾构隧道管片壁后注浆材料、注浆参数、二次补浆、各项掘进参数对地表隆起和沉降变形的影响;探究在苏州粉质黏土及粉砂地层条件下较小的隆起和沉降槽范围。
Combined with the practical experiences of shield tunnelling method from Lindun station to Cangjie station in the 1 st line of Suzhou subway project,we have been working hard to explore the characteristics of uplifts and settlements which are caused by tunnel boring machine working in silty clay and silty sand stratum of Suzhou under normal working condtion. We still made great efferts to find out the impact of grouting matrials, grouting parameters, second grouting and the boring parameters on the uplifts and settlements of the earth＇ s surface. The most important thing is how to control the uplifts to be smaller and the range of the settlement groove under the condition of silty clay and silty sand stratum of Suzhou.
