摘　　要：首先分析了边坡工程存在的耐久性问题,提出边坡工程抗疲劳、抗风化和抗腐蚀设计的思路.边坡工程存在合理的服役寿命,在风化、动荷载作用以及腐蚀环境下,边坡岩土的工程性能和锚固体性能将产生劣化,直接影响到边坡工程的安全性及耐久性.边坡工程耐久性设计是确保边坡长期稳定的重要措施,应全面考虑时间效应的抗腐蚀、抗疲劳、抗风化等问题的工程设计方法.提出边坡工程的耐久性研究应在:边坡所处环境作用及其对耐久性的影响、边坡工程耐久性劣化机理、边坡工程耐久性设计、在役边坡工程耐久性评估及其服役寿命预测四个方面开展进一步的工作.The durability of slope engineering is firstly analyzed,and the ideas of anti-fatigue,weathering-resistance and corrosion-resistance designs are proposed.There is a reasonable service life for slope engineering;under weathering,dynamic loads and corrosive environment,the engineering performance of rock and soil as well as the performance of anchorage body are degraded,which are directly related to the safety and durability of slope engineering.Durability design of slope engineering is the important measure to ensure the long-term stability of slope.Therefore,under the long-term effect,the corrosion-resistance,anti-fatigue,weathering-resistance,and other problems shall be fully considered in the engineering design.To this end,the research on durability of slope engineering can be developed from four aspects： environment of slope and its influence on durability,degradation mechanism of slope engineering durability,durability design of slope engineering,durability assessment of in-service slope engineering and prediction of its service life.
