摘要
通过从花岗岩残积土中分离出云母 ,按云母含量的不同配制试件进行承载比试验、回弹模量试验 ,研究云母含量对花岗岩路基土工程性质影响的复杂规律 ,探讨花岗岩路基土工程性质变化的机理。
The effect of mica content on the engineering characteristics of granite subgrade soil is studied,by separating mica from granite residual soil and forming the specimen according to different mica content, and conducting CBR test and resilience modulus test. The change mechanism of the granite subgrade soil is inquired.
