METHOD FOR DETERMINING MAINTENANCE OF A BRIDGE CONNECTION PART USING ACCELERATION SENSORS

摘要

The present invention relates to a method for bridge connection portion maintenance determination using an acceleration sensor. The present invention includes a step in which the acceleration sensor is attached to a vehicle; a step in which the vehicle to which the acceleration sensor is attached is driven on a bridge connection portion; a step in which a maximum instantaneous vibration value is calculated based on data measured by the acceleration sensor while the driving is performed on the bridge connection portion; a step in which the maximum instantaneous vibration value is applied to reference levels; a step in which a differential settlement slope of the bridge connection portion is measured when the maximum instantaneous vibration value is equal to or higher than setting levels of the reference levels; and a step in which it is determined whether or not to perform maintenance on the bridge connection portion by comparing a measured differential settlement slope value of the bridge connection portion to a reference slope value. According to the present invention, it can be determined with ease and accuracy whether or not to perform the maintenance on the bridge connection portion where a differential settlement occurs. In addition, inspection equipment has simple component configuration data production is simplified.
