Triaxial tests on three types of soil–rock mixture (S-RM) samples with the same rock block content, but different grain size distributions, were performed in this study. To better understand meso-mechanical behavior mixtures, one set containing "oversized blocks" was designed. The oversized blocks other two sets handled using equivalent weight replacement method and similar translation method. On basis, effect distribution mechanical properties mixtures explored. interlocking breakage large...
This paper documents the emergency breaching of an approximately 110-m-high landslide dam that was created at Tangjiashan during 2008 Wenchuan earthquake China’s Southwest Sichuan Province. As measure, a 13-m-deep channel excavated to reduce volume and head released water create controlled flood intended prevent catastrophic consequence for 1.2 million people downstream. From detailed monitoring survey works carried out after break it found (1) initiated pool level 742.1 m with estimated...
Although soil–rock mixtures (S-RMs) exist extensively on Earth's surface, their mechanical behaviors remain elusive. In this study, a series of large-scale direct-shear tests was conducted to investigate the S-RMs composed weathered basalt with different rock block contents, including stress–strain relationship, dilatancy, particle breakage, and shear strength. The results indicate that S-RM shows more pronounced strain-hardening behavior as its content increases. For there is power law...
Breakage of particles will have greatly influence on mechanical behavior granular material (GM) under external loads, such as ballast, rockfill and sand. The discrete element method (DEM) is one the most popular methods for simulating GM each particle represented its own. To study breakage mechanism breakage, a cohesive contact mode developed based GPU accelerated DEM code - Blaze-DEM. A database 3D geometry model rock blocks established scanning method. And an agglomerate describing block...
