摘要
以辽宁西部冻土为研究对象,模拟现场地下水位,对10种重塑土进行了大试件防冻害置换层参数确定试验研究。试验结果表明:对于辽宁西部季节性冻土,当置换层位于地下水位以上30cm、最大冻深的62%,且厚度为冻深的30%时,有明显的防冻害效果。
Taking the case of frozen soil in Fuxin city of Liaoning province,the frozen-heave factor of ten kinds of frozen soil have been experimentally studied under the condition of analogizing groundwater level.The test results indicate:there is a obvious effects of anti-freezing for the frozen soil in Fuxin city of Liaoning province when replacement layer is above the groundwater level about 30 cm,the largest deep-freeze for 62% and the thickness of the deep freeze 30%.
