Abstract

The red clay has high moisture content,high plasticity,high void ratio and other special engineering properties,especially when the subgrade surface dehydrates,it shrinks and cracks,caused the subgrade to have some diseases.Taking the subgrade filling from the Liupanshui inner Expressway as the research object,doing the experiment during wet and dry cycles when the red clay on the condition of 105 C and 34 C,and researching the relationship between the fissure ratio and the cycle index under wet and dry cycles.Research shown that the fissure ratio increasing with the increasing of the numbers of the wet and dry cycles,in the first two cycles it increased significantly,the last three cycles increased slowly,this phenomenon shows that the influence of the first two cycles on the crack of red clay is larger.That the ratio of the fissure ratio under the condition of 34 C to under the condition of 105 C increasing fast with the increasing of the moisture content and then reduce,reaching the maximum when the moisture content is optimum moisture content.
