摘要:
路基冻胀是季冻区常见的道路工程灾害,影响因素复杂且相互耦合。本文针对现行冻胀规范仅考虑土质条件和含水率两种影响因素的局限性,基于以往研究成果和综合判别,明确了含水率、温度、压实度和土质条件是路基冻胀的主要影响因素。以哈尔滨周边有代表性的季冻区道路为例,构建了上述四种因素耦合下的季冻区路基冻胀率计算公式,并采用层次分析法得到土质条件、含水率、温度及压实度对冻胀的影响权重分别为:0.47、0.21、0.18和0.14。新的计算公式能够反映多因素耦合下季冻区路基土的冻胀特性,为季冻区道路工程防灾减灾及相关规范完善提供了借鉴。
Abstract:
Subgrade frost-heaving is a common engineering problem for roads in seasonal frost regions, and its influences are complex and inter-coupled. In view of the limitations exist in current codes related to frost-heaving, where only the effects of soil properties and moisture content are taken into consideration, in this paper, the water content, temperature, compaction degree and soil conditions are regarded as the main factors influencing the frost-heaving of the roadbed through analysis and comprehensive judgment to previous research results. Take the typical roads around Harbin which is located in seasonally frozen regions as examples, a four-factor coupling calculation formula used for the frost-heaving ratio of subgrade in seasonal frost regions was established. The weight of soil conditions, water content, temperature and compactness on frost-heaving is 0.47, 0.21, 0.18 and 0.14, respectively, which were given by using the analytic hierarchy process. The new formula can reflect the frost-heaving characteristics of subgrade in seasonally frozen regions effectively by taking consideration of the multi-factor combined effects, and it will provide some references for the disaster prevention and mitigation and the perfection of related criterions for road works in seasonally frozen regions.
