摘　　要：电厂建设过程中场平形成的高填方边坡是威胁电厂安全的危险源之一。对高填方边坡进行综合分析有助于了解边坡失稳普适性规律,为同类边坡治理提供理论依据。通过对印尼某电厂高填方边坡进行地质勘测、稳定性评价、数值模拟、长期监测,综合探讨高边坡变形机理和防治措施的可靠性。研究结果显示:填方高边坡破坏模式主要是围绕软弱结构面,如表层填土和煤层等滑移或出现不均匀沉降;坡面防护体系、坡体内加筋格栅等防治措施可有效提高高填方边坡的稳定性;长期监测是评价边坡加固可靠性的重要依据,也是提前评价边坡潜在隐患的重要手段。The high fill slope formed during the construction process of power plants is one of the dangerous sources that threaten the safety of power plants.Comprehensive analysis of high fill slopes is helpful to understand the universal laws of slope instability,and provide theoretical basis for similar slope treatment.The deformation mechanism and reliability of prevention and control measures of high fill slopes in a power plant in Indonesia are comprehensively explored through geological survey,stability evaluation,numerical simulation,and long-term monitoring.The research results show that the failure mode of high fill slopes mainly revolves around weak structural planes,such as sliding or uneven settlement of surface fill and coal seams.Prevention and control measures such as slope protection system and reinforcement grid inside the slope can effectively improve the stability of high fill slopes.Long term monitoring is an important basis for evaluating the reliability of slope reinforcement,and also an important means for early evaluation of potential hazards in slopes.
