盐渍土地基风积沙换填技术应用研究

摘要

文章依托新疆G216线五彩湾至大黄山段高速公路, 就地取材利用风积沙换填处理盐渍土地基.应用结果表明, 风积沙粒度较均匀, 拥有良好的弹性, 压缩模量较一般土高, 具有较好的抵抗破坏的能力.换填的路基工后沉降满足要求, 验证了该技术的可行性.%Relying on Wucaiwan-Dahuangshan Expressway section of Xinjiang G216 Line, this article uses local aeolian sand materials to replace and treat the saline soil foundation.The application results show that the aeolian sand has a uniform particle size, good elasticity, and a higher compression modulus than the general soil, and it has better resistance to damage.The post-construction subgrade settlement after the replacement meets the requirements, which verifies the feasibility of this technology.
