【摘要】 为探讨土石坝最优坝料分区方案,根据正交试验设计原理,对土石坝坝体设置不同分区并制定材料配置方案,进行渗流及坝坡稳定分析,讨论坝料的配置规律。结果表明,坝体两侧和坝底区域应配置强度高的材料,坝体中心区域配置防渗性能好的材料,坝体靠近下游侧区域配置透水性好的材料,由此规律得到的优化分区方案较传统坝型能够更充分地发挥坝体材料防渗和抗滑稳定作用。更多还原

【Abstract】 In order to explore the optimum material zoning scheme of embankment dam, a plan of building different subareas and dam material configuration schemes is proposed to analyze the seepage and slope stability of each scheme based on orthogonal experiment design theory, and then the dam material configuration rule is discussed based on experiment results.The results show that, compared with traditional dam type, the optimized zoning scheme can more fully play the role of dam material on seepage control and slope stability when configuring high strength materials on both sides of dam body and dam bottom, the materials with good anti-seepage performance in the center of dam configures and the materials with good infiltration capacity in the region near downstream side of dam.更多还原
