摘要
客运专线无碴轨道对线下工程的沉降所引起的轨道永久变形做出了更加严格的限制,为保证无碴轨道的稳定性,需严格控制桥梁工程的工后沉降。介绍无碴轨道桥梁沉降的观测方法,利用沉降观测资料分析、预测和控制工后沉降,将线下工程的工后沉降控制到限值范围内,以确保无碴轨道的安全。
Non-ballasted track of the passenger transportation special line has more strict restrict for the permanent track settlement to guarantee its stability. The paper introduced the observation method for the settlement of the bridges in the non-ballasted track. Using the settlement observation data, it can analyze, predict, and control the settlement to guarantee the track safety.
