摘　　要：由于沥青路面结构设计理论不完善、混合料设计方法不合理等问题,使得我国沥青路面早期病害严重,导致频繁的维修改造或重建,这给公路建设的可持续发展带来了很大的挑战。永久性沥青路面是指在设计年限内无结构性修复和重建,仅需根据表面层损坏状况进行周期性维修的路面。论文从结构原理、层位功能、混合料设计、施工质量控制四个方面,系统的阐述了永久性沥青路面设计的基本理念,并以广州到河源高速公路惠州段路面工程为例,提出适合该地区的永久性沥青路面结构方案。Now long-cantilevered steel canopy is applied in engineering, so in this paper the canopy is categorized. The merits and demerits is given and the load, loadcase, action are summarized, furthermore, the controlling factors for bars and the details of key joints are suggested. At last, based on above, a series of 6m long-cantilevered steel canopy are analyzed, in addition, the data of result and the section of every bars are investigated and all these data are analyzed and compared.
