Abstract
With the wide application of blasting technology, people pay more and more attention to the impact of blasting vibration on the surrounding environment and buildings. To blasting vibration analysis and evaluation of the effect on the stability of the skip shaft, belt bridge based on the large finite element analysis software ANSYS Workbench entity unit model, the belt of the bridge structure modal frequency and applying 2 cm/s numerical simulation of blasting vibration load was the response of the study. The calculation results show that the maximum stress value is 0.0063 MPa, belt bridge in belt bridge at the top of the column, in the concrete design tensile strength of 1.43 MPa. The maximum strain of the belt bridge is 5.05×10-8, which is within the allowable elastic deformation range of the building, and is far less than the ultimate tensile strain of C40 concrete 1×10-4. The skip well is in a stable state.
