Abstract
In order to study the attenuation law and mechanism of shear strength of gravel soil under long-term immersion.In this paper,the mechanism of shear strength change,microstructure evolution and interaction between cementing materials and particles are systematically analyzed through the test of gravel soil samples.The result shows that the shear strength of gravel soil decreases with the extension of soaking time,and the change of microstructure is the key reason,which is affected by mineral composition and particle gradation.关键词
