内容記述 | This paper deals with the stability analyses of landslide slopes by the two-dimensional observations and analyses of groundwater pressure. In the landslide slopes having an inclined groundwater flow or having the multi-stratums with the different coefficients of permeability, the groundwater pressure can not be obtained from the static pressure calculated from the groundwater level since the vertical distribution of the groundwater pressure is not static. In this case, the observations and analyses of groundwater pressure should be considered to be a two-dimensional flow systems in a vertical section. And the distribution of pore water pressure along the slip surface used for the stability analyses should be determined from the water pressure using the finite element solution of groundwater flow. In Higashi-mushigame landslide and Matunoyama-koshi landslide, the groundwater pressures were measured by using the observation boreholes having a screened section not along all its length but only at the desired depth. The numerical models having the multi-stratums with the different coefficients of permeability were by trial and error identified by the finite element method so that the numerical results may agree with these field measurements. The stability analyses of landslide slopes using these distributions of pore water pressure along the slip surface provide the reasonable factors of safety. | |||||
