Abstract

본 연구에서는 BWIM(Bridge Weigh-in-Motion) 시스템을 기반으로 주행차량의 총중량 및 축중량 추정을 수행하였다. BWIM 시스템의 개발을 위해 차량 주행시험은 필수적이지만 그 비용과 시간이 많이 소요되고, 다양한 차량 주행 조건의 적용이 어렵다. 따라서 차량 주행시험의 비용 및 시간적 문제점을 보완하고, 주행 조건에 따른 다양한 교량응답의 확보할 수 있는 수치 시뮬레이션이 현장실험과 병행되어야한다. 본 연구에서는 교량의 동적특성을 반영하는 수치 시뮬레이션을 수행하여 교량의 응답을 획득하고, 통행 차량의 중량을 산출하는 BWIM 시스템에 적용하여 총중량 및 축중량 추정을 수행하고 정밀해석모델기반 과적단속기술에 대하여 제안하였다.

In this study, the estimation of axial load and total axial load was conducted using Bridge Weigh-in-Motion(BWIM) technique which generally consists of devices for measuring the strain induced in the bridge by the vehicles. axle detectors for collecting information on vehicle velocity and axle spacing. and data acquisition equipment. Vehicle driving test for the development of the BWIM system is necessary but it needs much cost and time. In addition, it demands various driving conditions for the test. Thus, we need a numerical-simulation method for resolving the cost and time problems of vehicle driving tests, and a way of measuring bridge response according to various driving conditions. Using a bridge model reflecting the dynamic characteristic contributes to increased accuracy in numerical simulation. In this paper, we conduct a numerical simulation which reflects the dynamic characteristic of a bridge using the Bridge Weigh-in-Motion technique, and suggest overload vehicle enforcement technology.
