METHOD FOR MONITERING BRIDGE SLAB USING PAVEMENT SURFACE CRACK PATTERNS
The present invention relates to a method of predicting the condition of a bottom plate of a bridge by using damage on a bridge deck pavement surface. The method includes the following steps of: obtaining image information by photographing the surface of a pavement material paving the upper surface of a bottom plate of a bridge; calculating a total damaged area of crack patterns occurring on the pavement material based on the image information of the pavement material; calculating a pavement material damage ratio value which is a ratio of the total damaged area to the total area of the bottom plate of the bridge; and inspecting the bottom plate of the bridge if the pavement material damage ratio value is no less than a set value. According to the present invention, the method is capable of easily and safely predicting the condition of a bottom plate of a bridge by predicting the condition of the bottom plate of the bridge through an inspection on the condition of damage on a pavement material paving the upper surface of the bottom plate of the bridge.
본 발명은 교면포장 표면손상을 활용한 교량바닥판상태 예측방법에 관한 것으로, 본 발명은 교량 바닥판의 상면에 포장된 포장재의 표면을 촬영하여 영상정보를 획득하는 단계; 상기 포장재의 영상정보로 포장재에 발생된 크랙패턴들의 총손상면적을 산출하는 단계; 상기 교량 바닥판의 총면적대비 총손상면적의 비율인 포장재손상비율값을 산출하는 단계; 상기 포장재손상비율값이 설정값이상이면 교량 바닥판을 점검하는 단계;를 포함한다. 본 발명에 따르면, 교량의 바닥판 상면에 포장된 포장재의 손상상태를 검사하여 교량 바닥판의 상태를 예측하여 교량 바닥판의 상태를 안전하고 쉽게 예측할 수 있다.
