摘　　要：大多数边坡在失稳以前都要经历一个长期的演化过程。因此,边坡演化过程的监测与评价非常重要。利用质量传输模拟方法,根据边坡地下水径流途径上任意两个已知点间的化学组分及同位素组成的变化,可以模拟水-岩之间质量传输的矿物形式、数量、淋溶速率及动态变化,其结果可以为边坡加固及滑坡预报等提供依据。以某边坡为例,介绍了该方法在边坡演化评价中的应用。In general,most slopes undergo a long evolution process before they fail. It is therefore important to monitor and evaluate the evolution process of slopes. By means of mass transfer modeling with variations of chemical and isotope composition along the groundwater flow paths,the mineral forms,quantity,rate and trend of the mass exchange between rock-soil materials and groundwater can be determined and the modeling results may provide scientific bases for slope reinforcement and landslide prediction. Taking a roadbed slope as an example,the application of the method to evolution evaluation of slopes is introduced.
