【摘要】 介绍了原状冻土单轴抗压强度的试验方法,分别在3个不同温度(-7 ℃,-15℃,25℃)下进行了单轴抗压强度的测定,试验表明原状冻土的抗压强度与温度之间也是符合线性关系的。试验的结论为冻土结构的设计与施工提供了参考。
【Abstract】 In this paper, uniaxial compressive tests on frozen soil in original state were made under three different temperatures (-7 ℃,-15℃,-25℃). The result showed that the uniaxial compressive strength of the original frozen soil has linear relation with temperature. It provided a reference for designing and construction of frozen soil structures.
