Analysis of seepage stability of large-scale landslide under water-level fluctuation and rainfall
Published 2021-07-01“…Landslide is widely distributed on the bank of the reservoir, which is easy to cause instability under the condition of water level fluctuation and rainfall.Donglingxin landslide accumulation body of the Sanbanxi Hydropower Station has a maximum thickness of 150 m and a total volume of 2 000×104 m3.The slope began to show large deformation at the first impoundment of the hydropower station in 2006, and the deformation is accelerated at the annual rainy season.Firstly, based on the field geological investigation and over ten years of monitoring data, the geological conditions and deformation law of the landslide body were obtained.Secondly, the saturated-unsaturated flow was calculated with different reservoir water levels fluctuation rates and the measured reservoir water level together with rainfall in 2019 by SEEP/W, and SLOPE/W was used to calculate the stability factors at different time.Results show that the slope is a super-deep landslide, which deformation process was deeply affected by the rise and fall of the reservoir water level and rainfall; The slope has characteristics of stagnant water, and the seepage process is complex; The stability coefficient decreases continuously in the process of reservoir water level rising while increases gradually in the process of reservoir water level falling; The stability declines rapidly with the combined effect of rising reservoir water level and heavy rainfall, and reaches the lowest value about 10 days after the flood season.The research can be used to guide the stability evaluation of large-scale landslide under water-level fluctuation and rainfall.…”

Discussion on precise location, focal mechanism and seismogenic mechanism of Jiaokou reservoir earthquakes
Published 2023-03-01“…The reservoir water infiltrates through the fracture fracture zone, the pore water pressure diffuses, the reservoir water softens and weakens the rock for a long time, causing the fault plane and some weak parts in the deep part to become unstable areas, and finally triggering the earthquake under the loading and unloading stress field caused by the change of reservoir water.…”

Published 2017-05-01“…The OLI support vector machine (SVM) classified data was successfully classified with regard to all six test classes (i.e., open land, residential land, forest, scrub land, reservoir water and waterway). The OLI SVM-classified data for the four seasons (i.e. winter, spring, summer and autumn seasons) were used for change detection analysis of six situations; situation1: winter to spring seasonal change detection resulted reduction in reservoir water mapping and increases of scrub land; situation 2: winter to summer seasonal change detection resulted increase in dam water mapping and increase of scrub land. winter to summer which resulted reduction in dam water mapping and increase of vegetation; situation 3: winter to summer seasonal change detection resulted increase in increase in open land mapping; situation 4: spring to summer seasonal change detection resulted reduction of vegetation and shallow water and increase of open land and reservoir water; situation; 5: spring to autumn seasonal change detection resulted increase of reservoir water and open land; and Situation 6: summer to autumn seasonal change detection resulted increase of open land. …”
