摘要
通过试验,研究了察尔汗岩盐用作路基填料的压实特性、抗压强度以及循环荷载下的变形性状。主要探讨了岩盐试样中细粒含量比例对试样压实特性的影响规律;天然岩盐抗压强度的大小分布,以及岩盐抗压强度与粒径、干密度、含水量的关系;交通循环荷载作用下,岩盐的动应变发展情况等。这些结论对盐湖公路建设具有一定的指导意义。
Based on a series of experiments, the mechanical properties of rock - salt, including compaction characteristic, compressive strength, and deformation behaviors under cyclic loading were studied. The following contents were discussed in detail： （ 1 ） Effects of small particle of rock - salt; （ 2 ） the value distributions of compressive s size, dry density and water content on compressive content of the samples on the compaction characteristic trength of nature rock - salt; （ 3 ） the effects of grain strength ; and （4） the development regularity of dynamic strain of rock - salt under traffic cyclic loading. The findings in this paper can be useful to the road construction in salt - lake areas in western China.
