技术领域Technical field
本发明涉及隧道沉降研究技术领域，具体来讲涉及的是一种隧道沉降变形预测方法。The invention relates to the technical field of tunnel settlement research, and specifically relates to a tunnel settlement deformation prediction method.
背景技术Background technique
隧道是埋置于地层内的工程建筑物，是人类利用地下空间的一种形式。然而，在百年的设计基准期内，隧道结构由于受到地基不均匀沉降、长期承受动荷载、混凝土收缩与徐变等因素的影响，往往会发生较大变形，从而增大隧道重大灾害发生的风险。Tunnels are engineering buildings buried in the ground and are a form of human utilization of underground space. However, within the design reference period of a hundred years, the tunnel structure often undergoes large deformations due to factors such as uneven settlement of the foundation, long-term dynamic loads, concrete shrinkage and creep, thereby increasing the risk of major disasters in the tunnel. .
由于两个矩形隧道节段之间的接缝变形可以直观反映隧道结构的变形情况，因此，工程中通常对接缝变形进行实时监测，以直观反映隧道结构的状况，从而避免重大灾害的发生，而现有的隧道中没有配置专用设备用以监测隧道的差异沉降变形情况，常用的方法之一是布点式的监控，测需要进行多断面反复操作，并受坐标控制点严重制约，监测误差大且操作繁琐，并不能有效反应隧道全长范围的位移变化，不便于研究。Since the deformation of the joint between two rectangular tunnel segments can visually reflect the deformation of the tunnel structure, the joint deformation is usually monitored in real time during the project to directly reflect the condition of the tunnel structure, thereby avoiding the occurrence of major disasters. However, the existing tunnels are not equipped with special equipment to monitor the differential settlement and deformation of the tunnel. One of the commonly used methods is point-based monitoring. The measurement requires repeated operations on multiple sections and is severely restricted by coordinate control points, resulting in large monitoring errors. Moreover, the operation is cumbersome and cannot effectively reflect the displacement changes across the entire length of the tunnel, making it inconvenient for research.
