Abstract The stepped overloaded plants were needed to be built on a landslide slope for a tungsten mine. Four rows of anti-slide piles were proposed for the treatment of sliding mass as well as the foundation of intra-plant step retaining wall and plants. In this case，the dual function of load-bearing and anti-slide could be utilized for the load-bearing and anti-slide piles. The optimization design and treatment methods for landslide under stepped overloaded plants were presented. Based on the transmit-coefficient method，an approach of resistance distribution of multi-row load-bearing and anti-slide pile was proposed considering the upper plant loads. With this method，the distributions of multi-row piles at the tungsten ore plant were calculated，and then the optimized design of load-bearing and anti-slide piles were conducted. Finally，with the long-term monitoring data of the landslide and the calculation results from finite element method，the rationality of the proposed method for the resistance distribution of multi-row pile was validated，and the applicability of the optimized design method for landslide treatment was verified. According to the inadequacies of resistance distribution of multi-row load-bearing and anti-slide pile in the current specifications，corresponding supplementary suggestions were proposed in this paper.
