冰水堆积体位于大古水电站选坝河段,其规模巨大,一旦发生失稳,将直接影响坝址水工建筑的安全.根据现场地质调查,分析堆积体物质组成及结构特征,建立地质计算模型,采用极限平衡分析方法,计算堆积体稳定性,计算结果表明,冰水堆积体整体处于稳定-基本稳定状态,前缘局部存在失稳的可能,对坝址影响较小,计算结果为边坡开挖及支护提供了科学的依据.

基于正交试验法,本文对粗粒土模糊集塑性硬化模型的8个关键模型参数进行敏感性分析.采用美国CASE试验数据库中的试验数据,以seid sand为例,通过大量计算,采用数理统计的相关理论,获取参数的期望和方差,经过比较,对模型的关键参数进行敏感性排序.计算结果表明,该研究方法可为模糊集塑性硬化模型参数的选取提供必要的参考,同时也可应用于该模型的二次开发,以减少其参数反演分析和筛选的工作量.
基于青藏铁路路基变形与地温观测数据,研究了多年冻土区路基下融化夹层特征及其对路基沉降变形的影响.结果表明:在已有监测场地中,青藏铁路沿线天然场地融化夹层发育较少;而路基下融化夹层发育较多,低温冻土区路基下融化夹层能够逐渐完全回冻使其消失,高温冻土区大部分路基下融化夹层有进一步发展的趋势.高温冻土区路基下融化夹层厚度的增加主要是由多年冻土人为上限的下降引起的.当融化夹层下部为高含冰量冻土时,融化夹层
