摘要
以北京地铁10号线二期工程为背景,详细分析土压平衡盾构穿越土砂复合地层过程中诱发的地层变形规律,同时分析盾构土压力、同步注浆压力及同步注浆量的控制情况,研究结果对指导施工及反馈隧道设计具有重要理论与实际意义,也可为类似研究提供参考。
Ground deformation rules of complex strata consisting of clay and sandy soil induced by EPB shield tunneling were studied in detail, with the second-phase project of Beijing metro Line 10 taken as background. Key parameters of shield machine were analyzed, such as earth pressure, quantity and pressure of synchronous grouting. These results are of theoretical and constructional importance for tunnel projects and can be referred to by similar studies.
