【摘要】 我国季节与多年冻土面积占幅员的2/3,地表土或土工结构物表层经历反复的冬冻、春融作用,使道路、工业与民用建筑、水工建筑物等工程产生灾害。利用改装的土工固结仪来试验研究冻土融化下沉特性,为正确选择地(路)基填料,防治冻害发生提供依据。更多还原

【Abstract】 Frost soil, whether seasonalfrost or permafrost, was widely spread in our country accounting to almost two-part of our mainland. Frost heaving in winter and thaw settlement in spring were usually observed in these area which took great damages to road,civil engineering construction and irrigation works there. The thawing compression characteristic of frozen soil was researched using oedometer test in this paper, which can be used to subgrade filling selection and frost damage prevention.更多还原
