Abstract

The invention discloses a non-navigable span pier collision avoidance monitoring system and a real-time diagnosis method. The system comprises sensors mounted on a bridge A, a bridge B and a bridge pier respectively, a data acquisition instrument and a data denoising instrument and the like. The monitoring system can realize online real-time monitoring of bridge pier ship collision, can directly and quickly carry out preliminary judgment on bridge damage degree in the first time of bridge pier ship collision, and can directly analyze impact force and important bridge pier structure reaction parameters and provide first-hand data support for bridge operation close, immediate maintenance decision, bridge pier component state assessment and damage identification; the monitoring system is reasonable in design principle, light in structure and high in impact force identification precision; the whole monitoring system is low in cost, and can be largely applied to the cross-sea and cross-river bridges without increasing engineering construction cost too much, thereby solving the problem of high cost of omnibearing collision avoidance monitoring; and the monitoring system is high in engineering applicability.

Description

technical field

[0001] The invention belongs to the technical field of bridge pier monitoring, and in particular relates to a monitoring system and a real-time diagnosis method for bridge pier anti-collision. Background technique

[0002] The international systematic research on the problem of ship collision with bridges began in the early 1980s, and then domestic and foreign scholars carried out a lot of research in the field of ship collision risk analysis and ship bridge impact force, and put forward the bridge anti-collision risk assessment for design method and impact force value method, and began to formulate relevant design specifications. In 1991, the American Association of Highway Engineers (AASHTO) published the first design guidelines for bridges subjected to ship impact. Since the 1990s, with the construction of large-scale cross-sea bridges, scholars at home and abroad have carried out a large number of bridge anti-collision technology researches based on the ...
