| Abstract: | Big-double-arch structure form is used in Nanjing Jiuhuashan Tunnel.The pruject features big fly-past,complex geology and higher demand on environment protection that make it very representative in double-arch tunnels. In order to protect the ancient city-wall where the tunnel passes through,it is necessary to estimate the safety of the ancient city wall under the influence of blasting of tunnel excavation.Several popular vibration velocity and vibration frequency formula are used to calculate the extent an... |
