新泻县境内每年都要发生多次滑坡,大部分滑坡发生在融雪期和暴雨期。新泻县枥尾市大野地滑区滑动面附近地下水位、孔隙水压随季节变化。在融雪期和暴雨期,滑动面附近的地下水位上升、孔隙水压增大。将地下水位换算成为孔隙水压计所埋设地点的静水压值,比较孔隙水压和静水压的变化,就可发现两者之间在时间上有
In Niigata Prefecture, many landslides occur on a yearly basis, and most of the landslides occur during snowmelt periods and storms. The groundwater level and pore water pressure near the sliding surface of Dayo ground slide area in Shanwei City, Niigata Prefecture changed with seasons. In the snow-melting period and heavy rain period, the groundwater level near the sliding surface rises and the pore water pressure increases. The groundwater level is converted into the hydrostatic pressure value of the place where the pore pressure gauge is buried. Comparing the change of pore water pressure and hydrostatic pressure, it can be seen that there is a time between the two.
