摘　　要：以新建沈阳南站哈大客专临时便线为例,以变更为路基的4号桥涵、处于新老路基交汇段的1号桥涵和6号桥涵为检测重点,通过对沉降观测数据系统综合分析评估,验证或调整设计措施,使路基达到规定的变形控制要求。分析、推算出最终沉降量和工后沉降,合理确定轨道开始铺设时间,确保客运专线轨道结构铺设质量。在此基础上,结合该客专便线的实际条件,给出客运专线安全监测技术方法,以期为以后类似工程提供可参考的依据。We take the Temporary line of new south railway station of Shenyang as an example and focus on No.4 bridge opening which is changed to the subgrade and No.6 and No.1 bridge opening which lie in the intersection of old subgrade and new subgrade.Through the comprehensive analysis and evaluation of settlement observation data system and Validation or adjust the design measures we can make subgrade meet deformation control requirements.Then analysis and calculate the final settlement and the post-construction settlement and reasonable track began laying time tomake sure the quality of the track structure of passenger dedicated line laying.On this basis combined with the actual conditions of the passenger dedicated line,safety monitoring technology for passenger dedicated line method is given.Basis to provide reference for similar works in the future.
