摘　　要：在东北高纬度冻土区的中俄输油工程是一条重要的能源线路,高寒地区冻土的冻胀性给输油工程的建设、运营和维护带来了更大的挑战。通过对中俄输油工程(漠河-大庆段)地质条件的考察与分析,系统研究了影响中俄输油工程岩土冻胀性的要素。结果表明:中俄输油工程沿线泥炭质黏土和含腐殖质粉质黏土是地质条件最差、冻胀灾害最严重的土体;天然含水率是影响岩土冻胀性最显著和最重要的因子;其他影响因素对岩土冻胀性影响较小,但不可忽视。The China-Russia crude oil pipeline erected in the high-latitude permafrost region of Northeast China is an important energy line.The frost heave of the permafrost in the alpine region has brought greater challenges to the construction,operation and maintenance of the oil transportation project.Through the investigation and analysis of the geological conditions of the China-Russia crude oil pipeline project(Mohe-Daqing section).The factors affecting the frost heave of the China-Russia crude oil pipeline project is systematically studied.The results show that peat clay and humus-containing silty clay along the China-Russia oil pipeline are the soils with the worst geological conditions and the most serious frost heave disasters;natural water content is the most significant and important factor affecting the frost heave of rock and soil;Other influencing factors have little effect on the frost heave of rock and soil,but cannot be ignored.
