摘要: 从试验模型、试验材料、试验装置及测试内容等方面制定了工程弃渣型坡面泥石流试验方案,拟定了模型试验 过程,降雨历时l6—18h,其中0—13h属于前期降雨阶段,降雨强度控制在6.8mm/(10min),分4次完成,每次降 1h,停2h;13h以后属于短历时强降雨阶段,降雨强度控制在16.7mm/(10min);分析了坡面渣体含水量、孔隙水 压力和地表位移高程随降雨历时的变化,揭示了工程弃渣型坡面泥石流形成过程的物理力学特性。

关键词: 工程弃渣型坡面泥石流, 形成过程, 模型试验

Abstract: Abstract:In vieWof test model,test materials,test equipment and testing content,one test plan of debris floWon slope of engineering slag was established.Meanwhile,the test schedule was clarified as that the rainfall duration is 16 -18 hours,of which 0-13 hours was the previous rainfall stage and rainfall intensity was 6.8 mm/10min completed in 4 times.And each rainfall and pause durations were 1 hour and 2 hours separately.It was the stage of the heavy rainfall of short duration after 13 hours during which rainfall intensity was 16.7 mm/10min. The physical and mechanical properties of the formation processes of debris floWon slope of engineering slag were demonstrated through the analysis of the change of moisture con- tent,pore water pressure and surface displacement elevation with rainfall duration of engineering slag on slope

Key words: debris floWon slope of engineering slag, formation process, model test
