城市浅埋隧道施工过程变形规律
|
摘要
城市浅埋隧道的施工会扰动周围的土体,形成地面不均匀沉降和塌陷,特别是城市浅埋隧道的施工路径对由于隧道开挖所产生的沉降与塌陷具有明显的影响,干扰隧道上方的地面交通、建筑等。使用数值方法模拟不同隧道开挖顺序,研究其施工路径对地层变形的影响规律,有着十分积极重要的意义。以武汉某隧道为研究对象,应用ANSYS有限元分析程序,对不同施工开挖顺序所产生的土体扰动变形规律进行了分析。得出了一些有益的结论并提出了有益的建议。
The surrounding soil mass was disturbed by the construction of urban shallow buried tunnel,then there was the differential settlement and collapse of surface,in which the influence of its stress pass was obvious,meanwhile the ground traffic and architectures were also disturbed.Therefore the soil layer deformation induced by the stress path of tunnel construction was studied by using ANSYS to simulate the excavation sequences of different tunnels.Based on the tunnel engineering in Wuhan,the deformation of disturbed soil was analyzed and its regularity was obtained.
