IntroductionRoad design for heliostat field is the important part in the design of solar power tower plant. To reduce power plant investment and improve the efficiency of heliostat field, road design shall be scientific, effective and reasonable. Method In this paper, the roads of heliostat field were divided into four categories: main road, radiation road, peripheral ring road and inter-heliostat road. The factors to be considered in the design were analyzed in detail, and the road layout, structural design and ancillary facilities were studied respectively.
Result The principles and requirements of the road layout are summarized. It is proposed that the pavement structure design should be based on the functional requirements, economic rationality, construction, local material and maintenance conditions. The pavement structure of inter-heliostat road and the road sign system in heliostat field is suggested.
Conclusion The paper is used for reference in the road design for heliostat field in the future.
