(汽—10级、汽—8级单辆主车;汽—10级单辆加重车;以及汽—8级、汽—6级车队相应的等代荷载) 为了发挥已建水利工程的效益,必须加速配套建筑物的建设。在本省需建的配套建筑物中,农桥所占的比重甚大。根据1980年3月在省水利厅召开的小型建筑物技术座谈会上的估算:仅30米以上跨距的农桥一项即需建10万多座,跨距在30米以下的更是面广量大。由于建桥任务十分繁重,如何提高设计效率是急需解决的问题之一。
(Steam-10, steam-8 single car; steam -10 single car; and steam-8, steam -6 fleet corresponding equivalent load) In order to give full play to the benefits of water conservancy project, Must accelerate the construction of supporting buildings. In the province to be built supporting buildings, Nongqiao accounted for a large proportion. According to the small building technology symposium held in the provincial water conservancy department in March 1980, it is estimated that only one agricultural bridge spanning more than 30 meters needs to be built over 100,000 and the span of 30 meters or less A large number of large. As the bridge construction task is very heavy, how to improve the design efficiency is one of the urgent problems to be solved.
