摘　　要：为了构建符合山区公路弃渣场动态工程特点的稳定性评价方法,实现建设与运行全周期安全管控,解决传统方法在覆盖阶段、管控内容及标准体系方面的不足。通过系统性分析弃渣场建造特征,建立覆盖场地-地基-边坡的全要素动态评价体系,具体包括:采用崩滑运动距离与行洪能力量化场地稳定性,管控地形改变引发的汇水安全风险;通过地基承载力计算与最大堆填厚度控制,实现超载工况下的地基安全评价;提出分级分类的边坡安全系数标准,基于不同工况(施工期/运营期)与工程规模实施永临结合的边坡动态稳定性评价。结果表明:在实际工程中,该方法有效整合了行洪影响、崩滑运动、堆填高度控制等关键因素,成功实现弃渣场全阶段(选址、堆填、运维)安全管控。与现行规范方法相比,其阶段覆盖完整度提升,风险管控维度增加地形改变、动态堆载等4项核心指标。提出的动态评价方法显著提升了弃渣场安全评价的系统性与工程适配性,即:空间维度实现“场地-地基-边坡”三位一体安全覆盖;时间维度贯穿“临时施工边坡-永久边坡”全生命周期;管控标准体现差异化分级特征。To develop a dynamic stability evaluation method for mountainous highway waste disposal sites that aligns with their engineering characteristics,achieving full-cycle safety management and control during construction and operation,and addressing the limitations of traditional methods in coverage stages,management content,and standard systems.By systematically analyzing the construction features of waste disposal sites,a comprehensive dynamic evaluation system covering"site-foundation-slope"was established,which includes:Quantifying site stability using landslide movement distance and flood discharge capacity to manage water convergence risks caused by terrain modification;Evaluating foundation safety under overload conditions through foundation bearing capacity calculations and maximum fill thickness control;Proposing graded and classified slope safety factor standards,implementing dynamic slope stability evaluations that integrate temporary and permanent conditions based on construction phases(construction/operation)and project scales.The results show that practical engineering applications demonstrated that this method effectively integrates key factors such as flood impacts,landslide dynamics,and fill height control,successfully achieving safety management across all stages(site selection,filling,and operation).Compared to existing standard methods,it improves stage coverage completeness and adds four core risk management dimensions:terrain modification and dynamic loading.The proposed dynamic evaluation method significantly enhances the systematicity and engineering adaptability of waste disposal site safety assessments:Spatially,it achieves integrated"site-foundation-slope"safety coverage;Temporally,it spans the entire lifecycle from"temporary construction slopes to permanent slopes";Management standards reflect differentiated grading characteristics.
