水泥改良盐渍土的力学性能研究

The mechanical performance study on cement improved saline soil

盐渍土由于盐胀性、溶陷性等特殊的工程特性不能够直接作为路基使用。通过掺入不同掺量的水泥对盐渍土进行改良,测试改良前后盐渍土的黏聚力、内摩擦角、无侧限抗压强度以及抗压回弹模量,并对其进行分析和评价,为今后的研究应用提供参考。

The saline soil can＇t be directly used in roadbed for its special engineering properties of salt expansion and solubility. Through adding different content of cement to improve saline soil, test the cohesion, internal friction angle, unconfined compressive strength and compressive modulus of resilience of saline soil before and after be improved, and carries on the analysis and evaluation, which provides reference for future research and application.
