| Abstract: | The finite element software ANSYS is adopted to analyze the blasting power of construction of small clear distance tunnel group on some expressway.As a consequence,the influential level of the earthquake wave produced by blasting construction of newly built tunnels during the drilling and blasting construction on established tunnels.This paper proposes the reference value of control speed for blasting construction of newly built tunnels and optimizes the excavation sequence of blasting construction of small... |
