摘要:
针对盾构近距离上跨施工对既有线的影响预测问题,采取有限元数值计算方法,以某地铁盾构隧道小间距上跨既有线隧道施工为例,通过Midas-GTS有限元软件建三维模型,对既有线的竖向和水平变形进行分析研究. 将数值计算结果与施工自动化监测结果对比,验证了数值计算分析的合理性. 结果显示盾构上跨施工导致既有线发生上浮,且盾构施工对水平向的变形影响远小于竖向,受影响范围主要在盾构与既有线交叉点两侧各1倍洞径范围内. 该研究为类似工程采取针对性措施提供了参考依据.
Abstract:
For predicting the influence of existing tunnel caused by up?crossing construction, taking a shield tunnel up?crossing construction as a case, we established the 3D model by using Midas?GTS software to study the vertical and horizontal deformation. The rationality of the numerical analysis was proved by comparing the simulation and the automatic monitoring results during construction. The results show that the shield construction uplifts the existing tunnel and the horizontal deformation is far less than the vertical. The influenced area is in the range of one tunnel diameters from each side of the cross points of the shield and existing tunnel, which provides a reference for similar projects.
