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.

所要求的资金将用于继续开发和改进适合于定量评估滑坡危害和风险的方法和工具。 七个潜在的研究课题，提出了这个总目标。 课题可供两个博士研究课题。及三名理学硕士生、工程硕士生及访问生。第一个拟议的主题将涉及开发一个通用的三维极限平衡方法的斜坡稳定性，适用于评估斜坡的稳定性，涉及复杂的，不对称的滑动面在土壤或岩石，特别注意外部负载。 第二个主题将旨在改进现有的岩石崩塌运动模型，并校准新模型，以便获得设计岩石围栏和其他补救措施所需的实际运动参数。 第三个将采用现有的动态分析模型来模拟涉及自发或地震液化的流动滑坡。 第四个专题将是校准一个模型，用于预测涉及岩石和冰川冰的重大雪崩的速度和跳动。 第五部分将研究滑坡运动模型与预测滑坡触发波的流体动力学工具的耦合。 第六个将适应现有的三维流动模型，考虑在移动的岩石雪崩逐渐破碎。 第七个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，开发一个新的滑坡分类系统。
