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 secondary lining engineering example of Baihua mountain tunnel of Wuyi hignway,taking the anti permeability label method as measurement method,water cement ratio as variables,age and extravasation material as measurement,this paper analyzed the influence 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.
