高速公路枢纽设置擎天柱广告牌安全性分析

Safety Analysis of Setting up Billboard Tower at Expressway Hub

高速公路枢纽范围是增设擎天柱类广告牌的黄金地带,高速公路枢纽车流转换量大,枢纽内信息载体单一,广告牌经济效益好,但公路枢纽增设广告牌的安全性问题尚未引起足够重视。以山西省陵侯高速公路常乐枢纽设置单柱四面式擎天柱广告牌工程为例,提出了目前高速公路枢纽设置广告设施应遵循的原则及具体要求,对单柱四面式擎天柱广告牌钢结构的力学特性进行受力分析,提出了类似工程的安全性分析方法,并为日后类似工程的设计、施工及后期管养提供参考依据。

The expressway hub is the prime area for setting up billboard towers, because the traffic flow conversion of the hub is large, the information carrier in the hub is single and the billboard has good economic benefits. However, the safety problem of the billboard tower at the expressway hub has not been paid enough attention. In this paper, based on the installation project of the single-column four-sided billboard tower at the Changle Hub of Linghou Expressway in Shanxi Province, the principles and specific requirements for setting up advertising facilities were proposed. The mechanical properties of the steel structure of the billboard tower was analyzed, and the safety analysis method for similar engineering was put forward. It can provide reference for the design, construction and maintenance of the similar engineering in the future.
