營造支撐群組位移監測及倒塌防止研究

Abstract

混凝土結構在灌漿時因受到載重及振動，若再加支撐不穩，則易崩塌，造成傷亡，此類災害在國內已是屢見不鮮，然尚未有一有效之方法監測，提供預警。本計畫即在於利用視覺辨識系統，可從工地外部或內部，全面、及時監測支撐群組位移，進而判斷其安全狀態，避免因使用應變計、變位計所導致之電線過多問題，亦可避免因量測振動頻率時外界雜訊過大而遮蓋欲量測訊號之問題。

Reinforced concrete structures are the most popular in this country. However, there are many construction disasters/accidents during pouring concrete due to construction loads, vibrations, impacts, and improper shoring. There is still not a real time monitoring system to avoid such tragedy.This investigation is to utilize the visual recognition method for monitoring the safety of the shoring system from either interior or exterior of the construction site. This system is superior to other methods in avoiding wires from strain gages, LVDTs, and the electronic noises from environment when measuring the natural frequency.
