大面积盐渍土地基处理措施

MEASURES FOR THE TREATMENT OF LARGE-SCALE SALINE LAND FOUNDATION

盐渍土广泛分布于在西北干旱地区,随着我国基础建设的需求越来越高,盐渍土的盐溶、盐胀、腐蚀等不良工程特性有时严重影响工程的安全性及建设成本。换填法和强夯法处理盐渍土的盐溶、盐胀、腐蚀等不良工程特性效果显著,以兰州中川国际机场三期扩建工程的盐渍土地基做研究对象,通过实验数据证明该处理措施效果良好,满足机场基础设计要求。

Saline soil is widespread in Northwest China.With the increasing demand for infrastructure construction in China,the poor engineering characteristics of saline soil,such as salt dissolution,salt swelling,corrosion,sometimes seriously affect the safety and construction cost of the project.The bad engineering characteristics such as salt dissolution,salt swelling and corrosion of saline soil treated by replacement method and dynamic compaction method are remarkable.This paper takes the saline soil foundation of Lanzhou Zhongchuan International Airport Phase III expansion project as the research object,and the experimental data prove that the treatment measures have a good effect and meet the requirements of airport foundation design.
