隧道水泥混凝土路面裂缝原因分析与处治研究

摘要

某新建高速公路的A1号隧道、A3号隧道、B2号隧道水泥混凝土路面在开放交通不到一个月就出现较多纵向裂缝和少量横向裂缝，通过钻孔取芯等方法对存在的质量问题进行分析，在事故分析时采取了相应的控制措施，经实施取得良好效果。由此在面对类似问题时可以及时的、有借鉴的、合理的去处理；同时通过质量问题的总结分析，对我们加强隧道水泥混凝土路面施工质量管理也起到了指导作用。%In less than a month after opening,longitudinal cracks and small amounts of transverse crack began to emerge on the cement concrete pavement of tunnel A1, A3 and B2. Some countermeasures are taken and brings good effect when making accident analysis through drilling core method to analyze the quality problems. Thus this provides some reference to solve similar problems timely and reasonably, as well as some guidance to strengthen the tunnel cement concrete pavement construction quality management.
