Development of methods and tools for landslide hazard and risk assessment

所申请的资金旨在继续开发和改进适用于定量评估滑坡危害和风险的方法和工具。提出了具有这一总体目标的七个潜在研究课题。这些主题可以提供两个博士和三个硕士学位的主题。在接下来的5年里，为学生和硕士学生和来访学生。第一个提出的主题将涉及发展一般的三维极限平衡法的边坡稳定性，适用于评估复杂的，非对称的滑动面在土壤或岩石中，特别注意外部荷载。第二个主题旨在改进现有的落石运动模型，并对新模型进行校准，以获得真实的运动参数，以满足岩石栅栏设计和其他补救措施的要求。第三个将采用现有的动态分析模型来模拟涉及自发性或地震液化的水流滑移。第四个主题将是校准一个模型，用于预测涉及岩石和冰川的主要雪崩的速度和跳动。第五部分将研究滑坡运动模型与水动力工具的耦合，以预测滑坡触发的波浪。第六部分将修改现有的3D流动模型，以考虑移动的岩石雪崩中的逐渐破碎。第七部分是地震震动对变形岩质边坡稳定性影响的初步研究。在赠款期间，我还计划继续在一个委员会工作，开发一个新的山泥倾泻分类系统。

The requested funding is intended to continue development and improvement of methods and tools suitable for quantitative assessment of hazards and risks from landslides. Seven potential research topics with this general goal are proposed. The topics can provide subjects for two Ph.D. and three M.A.Sc. students and for M.Eng students and visiting students during the coming 5 year period. The first proposed topic will involve the development of a general three-dimensional Limit Equilibrium method of slope stability, suitable for the assessment of slope stability involving complex, asymmetric sliding surfaces in soil or rock with special attention to external loads. The second topic will aim to improve existing models of rock fall motion and calibrate the new model so as to obtain realistic movement parameters, as required for the design of rock fences and other remedial measures. The third will adapt an existing dynamic analysis model to the simulation of flow slides involving spontaneous or earthquake liquefaction. The fourth topic will be to calibrate a model for the prediction of velocity and runout of major avalanches involving rock and glacier ice. The fifth will examine the coupling of landslide motion models with hydrodynamic tools for the prediction of landslide triggered waves. The sixth will adapt an existing 3D flow model for consideration of gradual fragmentation within a moving rock avalanche. The seventh will be a pilot study of the influence of earthquake shaking on the stability of deformed rock slopes. During the grant period I also plan to continue working on a committee developing a new landslide classification system.
