1、 辽宁科技大学本科生毕业设计 第 I 页摘 要本设计主要用于哈大客运专线高速铁路无砟轨道施工范围内的墩台、路基、隧道工程施工过程中的沉降变形观测。本管段要求构筑物应具有足够的强度、刚度、稳定性，满足耐久性要求，并强调与相邻构筑的变形与刚度协调统一，满足高速列车平稳、安全运营，以及旅客乘坐的舒适度要求。针对以上客运专线的特点，无砟轨道对路基、桥涵、隧道等线下工程工后沉降要求十分严格、标准高。虽然设计中对土质路基、桥梁墩台基础等均进行了沉降变形计算，采取了相应的设计措施，但设计的沉降分析、计算受勘测、设计、施工、质量监测等众多环节的影响，其精度仅能达到估算的程度，不足以控制无砟轨道工后沉降和差异沉
2、降。为确保线土建工程满足无砟轨道铺设条件的要求，在施工期间必须按设计要求进行系统的沉降变形动态监测。关键字：无砟轨道；变形监测；墩台工程变形监测；路基工程变形监测；隧道工程变形监测 辽宁科技大学本科生毕业设计 第 II 页ABSTRACTThe design is mainly used for the construction of the pipe within the piers, foundation, tunnel construction in the settlement process of observation.
