摘　　要：岩石的耐久性不仅与自身性质有关,还与岩石所处的服役环境有关。首先,介绍岩石耐久性的量化方法——MDE方法。然后,通过实际工程案例,在充分考虑岩石自身性质和所处的服役环境情况下,计算在一定设计年限下岩石剩余质量分数,量化岩石在当前服役环境下的使用寿命,判断此类岩石性质。最后,得出经过设计使用年限,基于MDE方法计算的此类岩石剩余质量分数满足使用要求,为其他工程中岩石耐久性评价提供借鉴与参考。The durability of rock is not only related to its own properties,but also to the service environment in which it is located.This paper briefly introduces MDE method.Through a specific project,the residual mass percentage of rock in a certain design life is calculated,the service life of rock in the current service environment is quantified,and the properties of such rock are judged by taking into full consideration the nature of rock itself and the service environment.It is concluded that the residual mass percentage of such rocks calculated based on MDE method meets the use requirements after the designed service life,which can provide reference for the evaluation of rock durability in other projects.
