盐渍土力学性状改性试验研究

根据盐渍土的物理化学性质 ,采用掺入消石灰或水泥进行处理 ,改性后混合料的击实试验、抗剪强度试验、承载比 (CBR)试验和回弹模量试验结果表明 ,盐渍土掺入消石灰或水泥改性后 ,混合料的性状得到了明显的改善 ,改性后的混合料可用于路基填土。

Testing Study on Mechanical Properties of Saline Soil

Based on the physical and chemical properties of saline soil the treatment of the soil is carried out by mixing lime or cement.The compaction test, shear strength test, CBR test and resilience test for the mixing soil have be done, and it is shown that the properties of the mixture of soil-cement (2%,3%,4% Portland cement) or soil-lime (2%,4%,6% lime) are greatly improved.The improved mixture of saline soil and cement (or lime) can be used to the filling of subgrade.
