摘　　要：在单元可靠性分析的基础上,以路网综合效益最大作为优化目标,并考虑道路建设的投资约束,建立公路网建设投资优化模型。利用该方法确定的规划公路网建设项目,不仅实现了建设资金的有效利用,而且满足了路网系统和道路单元的交通需求的不断增长。实例表明,该方法具有较强的实用性及可行性。Depending on the reliability theory,the investment optimum model of road network is built,taking the integrated benefit of the road system as optimization objective and letting the investment of road construction as restriction condition.The construction project identified by this method are not only to realize the utilization of construction capital effectively but also to meet continual increasing traffic demand.In the end of the paper,an example is given to illustrate the practicability and feasibility of the method.
