摘要: 新建哈尔滨至大连客运专线是我国在中-深季节冻土区第一条建设运营的高速铁路,其社会、经济意义十分突出. 为了解该铁路路基变形及其与环境变量之间的关系,在哈大高铁沈哈段沿线布设了15个路基监测断面以进行地温监测和路基不同分层的变形监测,同时开发升级了哈大高铁长期监测系统软件YH-FSMS,用于控制数据的采集、存储、传输和分析工作,并通过通讯网络实现了远程传输和控制. 通过对开通运营后第一个冻结-融解期的监测数据分析,哈大高铁长期监测系统运行基本正常,获得的监测数据真实可靠,能够为季节性冻土区高速铁路路基变形状况评价提供支撑. 利用长期监测系统对典型路基地段进行了连续监测,分析了路基冻融变形机理及其环境影响特征,并据此提出保障路基热平衡状态、改善路基系统水热条件、减弱路基变形影响要素的工程补强措施. 该系统的建立为路基冻胀变形实时监控和预警提供了科学依据,也为开展冻土区相关工程研究提供了技术示例.

Abstract: Harbin to Dalian Passenger Dedicated Line (HDPDL) is the first high-speed railway in cold regions in China, which has prominent social and economic significance. In order to understand the embankment deformation and its controlling factors, 15 monitoring sections were setting up in the sections along the HDPDL from Harbin to Shenyang. The ground temperature, water content and deformation in different layers were monitored. A long-term monitoring system software, named YH-FSMS, was also developed and upgraded, and then data collection, storage and transmission can be remotely operated. Analyzing the monitored data in the first freezing-thawing period after the system in operation revealed that the long-term monitoring system is in well operation and able to provide sufficient and reliable data for the HDPDL. It also can be used in embankment deformation evaluation system for high-speed railway in seasonally frozen soil regions. The deformation mechanism of the embankment and its influencing factors were analyzed based on the continuously monitored data at some typical embankment sections, and then some engineering measures are put forwards, including improving thermal equilibrium state, changing water and heat state and weakening deformation-increasing factors. The establishment of the monitoring system not only provides real-time monitoring data and frost heaving alerting, but also provides a technical example for cold region engineering research.

Key words: seasonally frozen soil regions, passenger dedicated line, long-term monitoring system, roadbed, frost heave
