| It is significant to study on the the regularity of stress and deformation of bridge caused by underground mining, not only for the construction of bridge in mining area ,but also for mining under a bridge. Taking a steel concrete continuous bridge as a model , build a 3D spatial model with ANSYS. Using this model , we analyse and elaborate the bridge's first,third,synthesis stress and damage distribution and regularity in different situations. With the approach of MATLAB and EXCEL, we have numeric analysis. Based on the above result, we get the allowable ground surface deformation and forecast the allowable mining thickness. |
