Abstract
The infiltration line is the lifeline of rock slopes in open-pit mines. This work focuses on the non-constant seepage problem of the highly-steep rock slope of the Sanshandao open pit mine in Shandong Province. Considering the seepage of the same section is different from that of the same infiltration line, the equilibrium equation is used to solve the solution of the infiltration line equation. The simulation is carried out by using Seep/W. The theoretical calculation results are compared with the simulated values to verify the correctness of the infiltration line equation. At the same time, the infiltration line equation is applied to the engineering practice, fitting observed water level of the reservoir, and analyzing variation of the infiltration line in combination with data of observational wells. Then using the ABAQUS fluid-solid coupling model, we analyze the plastic zone and safety factor of the tailings slope. The results show that the maximum error of the solution of the infiltration line equation to the simulated value is 0. 01%, which satisfies the actual requirement. The data of the observation well of the infiltration line is basically consistent with the theoretical calculation data with the maximum error 0. 75m, which proves the theoretical reliability. The rise of the water level of the tailings increases the plastic zone, and the safety factor and the wa-ter level change curve of the tailings is of"V" shape. When the water level is 100m, the safety factor is 1. 06, which is in the limit equilibrium state. At the same time the water level should set to be below -45m. These data provide a basis for the later establishment of water level of the reservoir.关键词
