摘要
西南地区红粘土分布广、起伏大,机场地基处理技术要求较高。粘土基试验,探讨某机场红厚度小于10 m的红粘土地基,采用不同能级的铺垫层强夯法和直接强夯法处理后的加固效果。通过单点夯击试验、地面平均夯沉量观测和波速测试等一系列试验手段,表明红粘土地基经强夯处理后,可满足机场设计要求。
The red clay is distributed diffusely and unevenly in the southwest of China,so it brings a high demand for disposing the base of airport. The examination works for different disposing efforts on the red clay where thickness is less than 10 meters series of tests such as single point of observations and wave velocity,the red airport design requirement. by the way of dynamic consolidation using cushion or none. After a dynamic consolidation method, the average amount of earth subsidence clay foundation treated with dynamic consolidation method is met the
