粉煤灰高性能混凝土在公路隧道二次衬砌中的应用

The application of high-performance coal ash concrete in the technology of quadratic tunnel lining of road tunnel

通过室内试验,结合青海公路湟源至倒淌河一级公路隧道二次衬砌的施工,采用三掺技术的粉煤灰高性能混凝土,克服了隧道常见的渗、漏水病害,取得了明显的经济效益和社会效益。

Combined the experiments in the laboratory with the construction of the arterial road tunnel's quadratic tunnel lining, a new techniques-road tunnel's quadratic tunnel lining has been applied in one section of the Qinghai Road (from Huangyuan to Daotang River). This paper introduces the ratio of mixture of high-performance coal ash concrete, its dynamics performance and the application effect.
