近年来,我国对水泥混凝土路面的设计理论、方法和参数进行了大量的研究,并取得了重大成果,但没有对路面进行可靠性的研究,如果一条路尽管其技术性能指标都很高,而可靠性不高的话,它的质量就不能说是好的,因此,需对路面结构的可靠性进行分析研究。 In recent years, a great deal of research has been done on the design theory, methods and parameters of cement concrete pavement in our country, and great achievements have been made. However, the reliability of pavement has not been studied. If one road has high technical performance index, If the reliability is not high, its quality can not be said to be good, therefore, the reliability of the pavement structure needs to be analyzed and studied.
