| 摘 要： | 对广州地铁三号线汉溪站–光明路站–番禺广场站3个典型断面的盾构隧道围岩稳定性进行了二维s模拟计算,分析了盾构施工对周围环境的主要影响因素,并采取了处理措施。数值模拟结果显示,围岩最大变形不超过8 mm,地表最大沉降量在1 mm左右,说明采用盾构施工隧道围岩支护体系是稳定的,通过在盾构实际施工过程中实施适时监控量测-反馈-处理措施的技术手段,可使其对周围环境的影响控制在最小范围。

| Abstract: | This paper conducts 2D- simulation calculations in the stability of rocks surrounding the three typical profiles of hanxi, Guangminglu and Fanyuguangchang stations of line3, Guangzhou Metro that is constructed using the shield method and analyses the major affecting factors of shield construction on the environments and treating measures concerned. The calculation results have shown that the maximum deformation of the surrounding rock is lower than 8 mm with a maximum ground subsidence of about 1 mm and the supporting system of the shield construction is stable. The effects of the construction can be reduceol to the lowest, if the real time monitoring-feed tack-treating measuring technique is adopted. |
