滨海地区用盐渍土作为路基填料是交通建设需要解决的重大岩土工程问题之一。滨海盐渍土作为一种特殊土,具有溶陷、盐胀、腐蚀等不良的工程特性,为了解决滨海盐渍土的工程问题,进行了电石灰改良盐渍土路基填料的液塑限试验、室内CBR试验、回弹模量试验、干湿循环试验和冻融循环试验。试验结果表明,盐渍土经电石灰改良后,其物理、力学性能得到了有效改善,能够用于滨海地区高速公路路基修筑。该研究成果对滨海地区盐渍土路基的修筑具有参考价值。
Saline soil as a subgrade filler in the coastal area is one of the major geotechnical problems to be solved in traffic construction. Coastal saline soil as a special kind of soil has such poor engineering characteristics as dissolution, salt expansion and corrosion. In order to solve the engineering problems of coastal saline soil, the liquid- Indoor CBR test, rebound modulus test, wet-dry cycle test and freeze-thaw cycle test. The experimental results show that the improved physical and mechanical properties of saline soil after being improved by electrogalloy can be used to construct highway subgrade in the coastal area. The research results have reference value for the construction of saline soil subgrade in the coastal area.
