摘　　要：结合武易高速公路百花山隧道二次衬砌工程实例,以抗渗标号法为测试方法,水灰比为变量,龄期和外掺料为衡量,分析了C30混凝土在不同水灰比下对抗渗性能的影响,指出水灰比是混凝土抗渗性能最重要的因素。Combining with the se condary lining engineering example of Baihua mountain tunnel of Wuyi hignway, taking the anti pe rmeability la-bel method as measurement method, water cement ratio as variables, age and extravasation material as measurement, this paper analyzed the in-fluence of C30 concrete to impermeability under different water cement ratio, pointed out that the water cement ratio was the most important factor of concrete impermeability performance.
