| 摘 要： | 黄土斜坡灾害已经成为黄土地区农村城镇化及交通建设的瓶颈,是当前地质灾害领域的研究热点.因震(振)动影响而降低黄土强度、改变黄土自身结构形态的研究是揭示黄土斜坡灾变机理的基础.基于GDS试验系统,采用应变控制等效正弦波逐级加载方式,进行马兰黄土动三轴试验；利用扫描电镜,观察马兰黄土试验前后微结构变化.试验结果表明:马兰黄...

| Abstract: | Failures of Loess slopes have been a bottleneck of rural urbanization and ground transportation construction in loess area.They and their hazards have been a current research focus of in engineering geology.One of the bases to reveal loess slope failure mechanism is to examine loess stress and microstructure changed due to effects of shock(vibration)or dynamic loading.This paper is based on the GDS Lab System,uses the equivalent sine wave loading gradually under strain controlling.Dynamic triaxial tests on ... |
