A probabilistic smart system to monitor unsaturated slope instability induced by rainfall infiltration
In Korea, slope failures are one of the most frequent natural hazards in heavy rainy season. Accordingly, the necessity of reasonable maintenance system for monitoring the slope is impending. It is well known that soil slope failures induced by rainfall infiltration are triggered by reduced unsaturated shear strength which is the result of matric suction reduction by the infiltration. Thus the consideration of unsaturated soil condition in the smart maintenance system for the soil slope structure is fundamental. Besides, the soil properties involved in a soil slope analysis imply many uncertainties. In addition, the consideration of spatial variability of soil properties results in more reasonable solutions to the slope stability analysis. In this paper, for developing more reasonable and quantitative slope maintenance system, statistical analysis scheme is combined with web based real-time data. A reliability analysis method is used for practical and simple application to the slope stability assessment method, considering unsaturated soil properties and shallow failure condition. The system reliability is checked by applying it to a real site. 1 INTRODUCTION
