Abstract: [Purposes]To evaluate the stability of slopes and optimize eco-friendly support schemes for a gully regulation project in Gansu Province, China,in support of ecological conservation and high-quality development in the Yellow River Basin.[Methods] The stability factors for sections 16-16 ' and 18- 18 ' were calculated under four loading conditions (self-weight,reservoir water pressure,seismic excitation,and road load) using both the Swedish slice method and Lizheng Software.Two support options-a counterweight retaining wall and a pile-plate retaining wall—were evaluated for their effectiveness. [Findings] The results of the Swedish slice method aligned with those from Lizheng software.Under selfweight and water storage conditions,all sections achieved "basically stable" status, while they were in an "under-stable" state under seismic load. The 16-16′ section was in an "unstable" state under road load. Both retaining wall types met the code requirements.[Conclusions] Considering economic eficiency,
constructability,and site conditions,the counterweight retaining wall is recommended as the optimal support scheme.While the pile-plate retaining wall offers greater flexibility and stronger lateral resistance, it requires more stringent foundation conditions and incurs higher material and maintenance costs.In comparison,the counterweight retaining wallfeatures mature construction techniques,bettr economic viability,and superior stability,making it more suitable for this project.
