Reservoir Seepage. Fugang Program Research

Along with the demand of work agriculture production and economic development, our country has no the place of condition reservoir in the construction mountain area and continuously was finished up to thousand reservoirs in plain, the construction of these plain reservoirs, reduced mining of local groundwater, well reasonable development and exploitation limited water resources, for the work agriculture of the region the production and city villager people's livelihood lived to arrive a good function and developed huge economic and social efficiency.Huanghe River water becomes a water resources of the guest of importance in Shandong more and more, therefore follow yellow the region build plain reservoir, adjust Xu Huanghe River water and have become urgent matter of the moment.As plain reservoir dam axis Wai longer, poor geological conditions, poor soil material for dam characteristics such as anti-seepage treatment is the key issue of plain reservoir construction. Seepage handled properly, may result in dam reservoirs or dam foundation Wai large amount of leakage can not be effectively water; may result in agricultural villages submerged behind the dam and land salinization; may result in penetration of a gradient greater than the allowable value of Yi to form a penetration and sabotage led to Dam, it should adopt effective anti-seepage treatment program.In this paper, Shandong Province, FuGang reservoir seepage is designed to rely on to explore the current anti-seepage treatment of plain reservoir engineering can be used when cutting seepage measures, analyze its seepage characteristics, construction technology, construction costs, seepage parameters and the application of the stratigraphic conditions, etc.; seepage by finite element calculation of natural seepage, horizontal impermeable, vertical anti-seepage effect of the program in impervious areas of examination, analysis of different levels of length and vertical anti-seepage seepage seepage volume and depth on the slope out of Yat lower degree of influence of parameters such as; comprehensive finite element analysis results and comparative analysis of the economy, choose the best seepage control.This text research expresses that vertical anti-seepage and seepage interception ditch can reduce reservoir to seep into quantity and ensure to ooze to flow a safety and ease after the dam a land time to living salt alkali to turn degree and effectively suppress the reservoir surrounding salt alkali in the land to turn to spread.
