摘要：In order to study the seepage problem of the slope, the seep/w module in geo-studio is used to analyze the sluice of the Tanzhuang reservoir dam in Liaocheng, and the finite element simulation analysis of the slope seepage under different working conditions is obtained. A series of physical quantities such as seepage velocity, seepage flow and saturation line under working conditions. At the same time, the influence of different anti-seepage materials on the seepage of the slope is analyzed. The best combination of anti-seepage effect and economic benefit is obtained. The analysis results show: (1) In terms of anti-seepage effect: Compared with no anti-seepage measures, horizontal anti-seepage can reduce the seepage velocity to 81% before, and the anti-seepage effect is ideal. The vertical anti-seepage effect in the joint action with horizontal anti-seepage is extremely significant, and the seepage velocity can be reduced to 78% before. (2) In terms of project cost: The price of the anti-seepage film is relatively low, but the laying area is large, which requires a lot of manpower and material resources. The pouring concrete anti-seepage wall has a higher cost and the construction is more complicated. For this project, laying an anti-seepage film is more economical. (3) Comprehensive view: In order to combine the anti-seepage effect with the economic benefit, the combined action of the anti-seepage membrane and the anti-seepage wall is the best choice, and joint anti-seepage can be carried out at important parts, and only horizontal anti-seepage can be performed at the secondary position. The results of this study can provide reference for the same type of project, reduce construction costs, and further improve the stability of the slope.
