- Abstract:
- Aimed at the problem of seismic safety research of seismic performance analysis of ground in-situ tall structures caused by tunnel blasting construction,we establish the analysis method of determining vibration load method of tunnel blasting work site and calculation equation of blasting vibration energy of tunnel construction,and then we discuss displacement field distribution and seismic dynamic response of tall structures of meteorological tower under the influence of underground tunnel blasting construction At last,we make comparative analysis of different dynamic responses at different positions of meteorological tower under the influence of underground tunnel blasting construction.The results show that the blasting seismic wave belongs to proximal pulse type,and the destructive potential ability of shear wave due to its failure energy and strength.Stress mutation phenomenon at the weak layer of high thin type structure of meteorological tower is obvious whose quality and stiffness mutated.And the top radar is strongly influenced by the lash effect and the amplification effect of blasting seismic dynamic response is obvious which reduces the seismic performance of ground high-rise structure seriously.
