【摘要】 季冻区路基冻融现象严重威胁着公路运营安全,其根本原因在于冻融作用会导致路基土力学参数变化。选取三种不同土样,通过三轴试验,测试得到了不同冻融循环次数下路基土抗剪强度的变化规律,为季冻区路基材料选取提供依据。更多还原

【Abstract】 In seasonal frozen regions,the serious threat of subgrade freezing- thawing to highway safety with the root cause of the changing mechanical parameters of subgrade soil due to the effects of freezing- thawing.Through the triaxial test with three different soils selected,it is observed of the varying pattern of subgrade soil shearing strength under the different number of freeze and thaw cycles,which provides a reference for the material selection for seasonal frozen regions.更多还原
