摘　　要：以松软土地区铁路某车站路基沉降及处理为工程背景,通过数值模拟提出了站台后填筑工况下的路基沉降控制方案,分析了周边基坑抽降水对路基的变形影响,通过调整扣件和注浆抬升恢复了无砟轨道平顺性。建设过程中要贯彻落实整体施工管理理念,统筹推进站前、站后及市政配套工程建设,避免因相关工程不同步实施影响高铁建设。Taking the subgrade settlement and treatment of a railway station in soft soil area as the engineering background, this paper puts forward the subgrade settlement control scheme under the filling condition behind the platform through numerical simulation, analyzes the influence of dewatering of surrounding foundation pit on the deformation of subgrade, and restores the smoothness of ballastless track by adjusting fasteners and grouting lifting. During the construction process, the overall construction management concept should be implemented, and the construction of pre station, post station and municipal supporting projects should be promoted as a whole, so as to avoid affecting the construction of high-speed railway due to the asynchronous implementation of relevant projects.
