Experimental study on remodeling strength of granular materials under different loads and lengths of timeHAN Liu(韩流)1, 2, ZHOU Wei(周伟)1, CAI Qing-xiang(才庆祥)1, SHU Ji-sen(舒继森)1, JING Hong-wen(靖洪文)2... function but are not correlated with remodeling time length. In situ experimental results indicate that the shear strength of reshaped granular materials in the internal dump is positively correlated......
characteristics and strength parameters of red-sandstone JIANG Jian-qing(蒋建清)1, 2, YANG Guo-lin(杨果林)1 1. School of Civil and Architectural Engineering, Central South University, Changsha 410075..., and shear strength parameters for red-sandstone with different water contents,different compactions, and different grain size distributions were obtained from the tests. A practical procedure of in-situ test......
