盐渍土地基风积沙换填技术应用研究

Applied Research on Aeolian Sand Replacement Technology in Saline Soil Foundation

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.
