水泥混凝土路面裂缝的分析及防治

从混凝土的结构组成、承载能力、周围介质等方面入手，分析水泥混凝土路面产生裂缝的原因，找出与之相关的因素，如基层的强度、混凝土的配合比、混凝土的养护条件及施工温度等。得出在施工过程中。如果采取恰当的措施加以控制，如提高土基及基层的强度、选择合适的水泥和骨料的品种、优化混凝土配合比设计、避免过高或过低温度施工、加强养护等，可减少或避免产生裂缝。

Technical Analysis and Preventive Measures of Concrete Pavement Cracking

From concrete composition, carrying capacity and environmental factor, the reasons of concrete pavement cracking are analyzed. The main factors include the foundation, mixing proportion, maintain conditions and construction temperature. In our practice, the cracking can be reduced even avoided to take correct measures in the process of construction, for example, improving the strength of foundation, selecting modest assortment of cement and pebble, optimizing the design of mixing proportion, avoiding too-high or too-low temperature, enhancing maintain and so on.
