Abstract

Abstract: The traditional mechanism of cement concrete slab faulting exists some inaccuracies,so some phenomena can not be interpreted.The interactions between cement concrete surface course and base course will theoretically lead to three basic damage types in base course,in other words,the base course will lose its integrity.Based on this proposition,the reason of cement concrete slab faulting is renewed.The new mechanism of cement concrete slab faulting has been proved by the investigation of the actual road.The new cement concrete slab faulting mechanism has some theoretical and actual significance for the prevention of cement concrete slab damage.

Key words: cement concrete, slab, faulting, mechanism

摘要： 现有水泥混凝土路面错台机理存在含糊不清的表述,无法解释水泥混凝土错台时的诸多表象。理论上,水泥混凝土面层和基层相互作用会引起基层出现3种基本破坏形式,从基层整体性的丧失出发,水泥混凝土路面的错台机理得到了全新的揭示。通过实际道路的现场调查,这种新的水泥混凝土路面错台机理得到了验证。新的水泥混凝土路面错台机理的认识,对于预防水泥混凝土路面破坏具有一定的理论和实际意义。
