山区通村公路低造价水泥混凝土路面结构研究

摘要

In order to make full use of paving resources, save project cost and improve pavement design quality, this paper starts from the affecting factors, such as traffic characteristics, soil foundation strength and paving materials to propose three such pavement structure forms as rock rip-rap cement concrete, small plate stone cement concrete and low intensity cement concrete, which correspond to construction resources features of country road in mountain area. Then mechanical analysis, with finite element software, and then economic comparison, is carried out in relation to the recommended pavement structures so as to determine the pavement structure with lowest project cost finally.%为充分利用筑路资源、节省工程造价、提高路面设计质量,从交通特征、土基强度、筑路材料等影响因素出发,提出了抛石水泥混凝土、小板块水泥混凝土、低强度水泥混凝土路面三种符合山区通村公路建设资源特点的路面结构形式.采用有限元软件对推荐的路面结构进行了力学分析,并对三种结构形式进行经济比较,确定出工程造价最低的路面结构类型.
