摘要
结合混凝土高温受损的特性,对杭金衢高速公路樊村1号隧道火灾后衬砌混凝土在高温下受混凝土内温度梯度剧烈变化而发生表面硬化、裂缝、颜色变化、集料变质、混凝土崩落等现象进行了分析,并提出了提高公路隧道抗火灾能力的措施。
Combined with the characteristics of damaged concrete, the lining concrete(No.1 Tunnel, Hangjinqu Expressway ) has been changed strongly after a fire. Under the high temperature, several special phenomena have been analyzed such as surface hardening, cracks, the change of color, aggregate deterioration and concrete collapsing. Then the correspective measures have been applied.
