Abstract

A 30 m fabricated prestressed concrete simply supported T-beam bridge uses a pile foundation as its lower structure. Owing to the filled engineering spoil at the abutment side, which is higher than the original ground line 11.87 m, 8 cracks formed in the side of 3 pier columns adjacent to abutment within the range of 1 m above the filling line. According to the shape and location of the cracks, the corresponding calculation model is established by dividing the pier column into two sections of above and below the soil. The causes of the cracks formation and their influence on the structure are analyzed quantitatively. The correctness of the calculation model is verified by disease phenomena detected subsequently. Considering the poor stability of the filling soil, the spatula around the pier was stratified and cleaned, and then the crack was stable and the shear deformation of the support was basically restored.
