Study on Confined Compression Test of Coarse-grained Limestone Soil
Taking the coarse-grained limestone soil as the research object, this paper carries out theconfined compression test for limestone soil with different coarse-grain content under 95%compaction and optimal moisture content, and studies the effects of P<sub>5</sub> content and P<sub>2...

| description | Taking the coarse-grained limestone soil as the research object, this paper carries out theconfined compression test for limestone soil with different coarse-grain content under 95%compaction and optimal moisture content, and studies the effects of P<sub>5</sub> content and P<sub>2-5</sub> content onengineering characteristics by analyzing the relationship curve between P<sub>5</sub> content and P<sub>2-5 </sub>content and sedimentation, compression modulus and void ratio. The results show that: when theP<sub>5</sub> content is less than 55%, the compression modulus increases slowly and the void ratio decreaseswith the increase of P<sub>5</sub> content; when the P<sub>5</sub> content is between 55% and 80%, the compressionmodulus increases rapidly and the void ratio almost doesn’t change with the increase of P<sub>5</sub>content;when P<sub>5</sub> content is more than 80%, the compression modulus changes slightly and the voidratio increases rapidly with the increase of P<sub>5</sub> content;with the increase of P<sub>2-5</sub> content, theskeleton effect is enhanced and E<sub>s</sub> is obviously increased when P<sub>5</sub> content is constant between 60%and 70%. The P<sub>5</sub> content plays a leading role in the engineering characteristics of coarse-grainedlimestone soil within a certain range. |
