光伏边坡稳定性多因素耦合分析及工程优化研究OA

The photovoltaic system on highway slopes is widely used in mountainous areas of southern China due to its dual functions of ecological restoration and energy supply.However,the self-weight of the photovoltaic system,the load of the support structure,and the multi-field coupling effect of the slope soil are prone to induce instability,endangering the engineering safety and power generation efficiency.Existing studies are mostly limited to the influence of single factors such as slope height and slope angle,and fail to systematically reveal the multi-scale coupling mechanism of"photovoltaic system-support structure-pile foundation-slope soil".This makes it difficult to guide engineering design under complex conditions.Based on the ABAQUS finite element platform,this paper uses the strength reduction method to calculate the safety factor and combines the L25 orthogonal experimental design to quantify the contribution of seven key parameters such as slope angle,slope height,and cohesion to stability,revealing the dynamic interaction laws between the photovoltaic system and the slope soil,and providing quantitative basis and theoretical support for the stability evaluation and safety design of highway slope photovoltaic projects.
