交通线路沉陷预计方法

Prediction Method of Traffic Line Subsidence

根据地表沉陷原理，基于褶曲构造地层、任意形状工作面条件下地表点在任意方向的移动与变形值预计方法，讨论交通线路遭受地表沉陷的破坏影响，论述地表沉陷区交通线路移动与变形预计方法，探讨交通线路安全性评估方法及其坍塌事故的防治措施。最后，列举了一个公路沉陷预计实例。

Based on the principle of surface subsidence and prediction method of movement and deformation values of certain surface point in arbitrary direction under conditions of fold tectostrati-graphy and workface with arbitrary shape, the destructive effect of the traffic line caused by surface subsidence is discussed in the paper, the prediction method of movement and deformation of the traffic line in surface subsidence area is also illustrated, and safety evaluation method of the traffic line and preventive actions against subsidence accident are provided as well. At the end of the paper, an actual example predicting subsidence of a highway is given.
