为探索合理的太阳能路面结构型式,提出一种内设拱室、导光体与太阳能电池的矩形导光混凝土空心板块结构,其中每个导光体是由平凸透镜、圆台形棱镜和圆柱形导光光纤复合而成的整体构造,平凸透镜作为进光端等间距布设于空心板块表面,导光光纤底面作为出光端汇集于拱室拱顶处,从而可将路表光能汇聚传导并投射至内置太阳能电池上进行光伏发电.首先,通过三维有限元建模模拟了空心板块路面结构的受力特点,确定满足承载能力要求的空心板决适宜长、宽、高分别为50、50、17 cm,拱宽、底厚、拱高、顶厚分别为26、5、5、7 cm;其次,采用光线追踪法仿真导光体的光路传播规律,并根据导光性能和经济性优选了导光...

In order to explore a reasonable type of solar pavement structure, a kind of rectangular hollow slab structure of light guide concrete with built-in arch chamber, light guide bodies and solar cell was proposed. Each light guide body was an integral structure composed of a planeconvex lens, a truncated cone-shaped prism and a cylindrical light guide fiber. The planeconvex lenses as light input terminals were arranged on the surface of hollow slab at equal intervals, and the bottom surfaces of light guide fibers as light output terminals were gat...
