Problems solved by technology

At present, many bridges in my country use pile foundations, many of which are erected in sea areas with harsh water conditions. During long-term operation, erosion is an important factor leading to pile foundation instability and bridge damage. For example, in 2008, A The Xian Bridge was eroded by the Qishan stream, causing the piers to fall and loosen, the bridge deck to sink, and the bridge was closed.

Embodiment Construction

[0028] The present invention will be further described below in conjunction with the accompanying drawings of the description.

[0029] Such as figure 1 As shown, a kind of bridge scour pit evaluation method based on real-time monitoring data processing of the present invention comprises the following steps:

[0030] The first step is to acquire the real-time monitoring data of original scour, and read real-time real-time monitoring of the original scour obtained by the displacement gauge and pressure sensor installed on the top support of the distributed pier, the pile side velocity meter in the water, and the underwater scour pit depth monitoring equipment. The data includes the displacement of the top of the pier, the vertical load and bending moment at the support, the water flow velocity at the side of the pile, and the depth of the scour pit of the pile foundation, and is stored in the form of an array, which is defined as unprodata{{u 1 , N 1 ,M 1 , V 1 , H 1

Abstract

The invention relates to a bridge pile health state evaluation method based on real-time monitoring data processing, which solves the problem that the bridge pile health state cannot be effectively evaluated compared with the prior art. The method comprises the following steps: acquiring the original scouring real-time monitoring data; performing simplified processing of real-time monitoring dataof erosion; establishing the dynamic and real-time finite element evaluation model of pile erosion, evaluating the health status of bridge pile foundation. The invention can quickly and effectively utilize the real-time monitoring data to evaluate the health state of the bridge pile foundation.

Description

technical field [0001] The invention relates to the technical field of big data processing, in particular to a method for evaluating the health status of bridge pile foundations based on real-time monitoring data processing. Background technique [0002] Bridges are important transportation hubs, and the healthy operation of bridges has a huge role in promoting traffic safety, people's lives, and social and economic benefits. At present, many bridges in my country use pile foundations, many of which are erected in sea areas with harsh water conditions. During long-term operation, erosion is an important factor leading to pile foundation instability and bridge damage. For example, in 2008, A The Xian Bridge was eroded by Qishan stream, causing the piers to fall and loosen, the bridge deck to sink, and the bridge was closed. [0003] It can be seen that the safety of bridge pile foundations is an important indicator reflecting the overall safety of bridges. If the health statu...
