Analytical Model of Bedding Rock Slope Instability Induced by Snowmelt-runoff Erosivity
摘要
Abstract
Considering the mechanical form of rock bedded slope under snowmelt infiltration, a finite element model on continuum saturated-un-saturatedseepageinbeddingrockslopeisproposedbasedontheUbiquitous-Jointmodelandtheseepagecharacteristicsofrockslopesnowmelt infiltration. Themodelisadoptedforitsabilityofdescribingthetransverselyanisotropybehaviorofrockbeddedslope. Meanwhile, itsnumeri-cal realization and convergence criteria are also studied. Comparison the results of a concrete seepage problem of bedding rock slope under snowmeltinfiltrationshowsthattheproposedmodeliscorrectnessandeffectiveness. Theinfluenceofsnowcoverthickness, tendencyandincli-nation of rock bedding plane on the stability of slope are analyzed. T his model can be extended to the stability analysis of reverse bedding slope and roller compacted concrete dam surface.关键词
