中小跨径斜拉桥拉索监测方案研究

Study on Stayed Cable Monitoring Scheme of Small-span and Medium-span Cable Stayed Bridges

受建设环境及经济条件的影响,监测中小跨径斜拉桥的拉索安全一般只能通过在部分拉索上布置的少量传感设施来完成。如何将少量传感设施布置在桥梁拉索的恰当位置并取得最接近实际情况的数据,已成为桥梁安全监测设计时需要处理的关键性问题之一,而恰当的位置只能通过拉索的相关性来确定。

Affected by the construction environment and economic conditions,the monitoring of stayed cable safety of small-span and medium-span cable stayed bridges is generally completed only through a few sensing facilities arranged on some stayed cables.How to arrange a few sensing facilities at the proper position of the bridge stayed cables and obtain the closest data to the actual situation has become one of the key problems to be handled in the design of bridge safety monitoring,and the proper position can be determined only by the relevance of the stayed cable.
