The course comprehends the methodology of analysis and deal with the problems of slopeland failure with geological knowledge and engineering technical. Contents show the influence and interaction between slope mitigation engineering and geology, include subjects of geology process, material factor, geological structures, and environmental factors of geology, such as geomorphology, plate tectonic motion and fault effect. As well as the method of engineering investigation and quantified of influence parameters. Last, the reconnaissance for slopeland disaster and practice of field investigation are also introduced to fulfill the skill of learner in the mitigation of a failure slope.
