摘要
哈尔滨至大连(哈大)客运专线地处冻土区域,受温度等因素的影响,易产生路基变形。通过哈大客运专线实地调查,选取沿线3个典型横断面进行了沉降变形、地温、土体应力、含水量4项内容1个冻融循环期的监测,监测分析结果与实际相符,为路基稳定性评价提供了依据,具有重要的工程参考价值。
Harbin-Dalian Passenger dedicated line locates in permafrost regions. It is influenced by such factors as the temperature, and subgrade deformation is easy to occur there. Based on field investigation, three typical cross sections along the line were selected and monitored for settlement deformation, earth temperature, soil stress, moisture content in a cycle of freezing and thawing period. The monitoring and analyzing results are consistent with the actual engineering, providing the basis for subgrade stability evaluation and important reference to projects.
