Model of reflection box culvert roof condition of corroding

The utility model provides a model of reflection box culvert roof condition of corroding for the concrete of simulation box culvert roof and/or the corruption condition of the interior reinforcing barof concrete, the box culvert roof comprises concrete and reinforcing bar. Wherein, the concrete is formed by a certain proportion of cement, thick aggregate, fine aggregate and water stirring, and the reinforcing bar is buried underground and is predetermine degree of depth department in box culvert roof top and bottom under the intact condition of box culvert roof, the model includes a pluralityof sections reference model, and every section reference model's concrete thickness progressively steadilys decrease. The utility model discloses a various detection method's validity, calibration method parameter can be tested in the aspect, on the other hand can draw the instrumentation test data under the various roof corruption circumstances with the help of this model before test on the spot, these data can determine
