| 摘 要： | 高速铁路无碴轨道形式，要求工后沉降不大于15mm，而结构物与路基的连接路段是刚性和柔性衔接段，往往是容易产生不均匀沉降的部位，应从设计、施工和维护的质量控制上最大限度地减少不均匀沉降，保证道路的平顺性以满足高速行车的要求。

| Abstract: | It is required that high-speed railway track without ballast subside less than 15 mm after settlement. The joint of structure and roadbed, which is the convergence of the rigid and flexible, are often prone to uneven subside. Uneven subside should be minimized by the quality control of design, construction and maintenance to make sure that the railway is smooth enough for high-speed lane. |
