Abstract:
Based on soil-structure dynamic interaction theory, aseismatic calculation is used for the analysis on portal section of highway tunnel for an important practical engineering project. The response of displace, acceleration and internal forces of structure are described. Results show that the locations of the basement of sidewall and the hance are weak points of aseismic under the situaition of artificial seisimic wave. The waveform of acceleration of structure is similar to the one input. These results provide some references for aseismic design.
