厦门仙岳山公路隧道爆破振动测试报告

Test report of vibration induced by blasting in Xianyueshan municipal tunnel in Amoy

文章论述了小线间距城市公路隧道爆破振动测试过程,分析了隧道纵向振速衰减规律、隧道横断面振速分布规律及隧道掌子面附近振动情况,提出了隧道各类围岩振速允许值和隧道振动安全判据。

In this article, the test of vibration induced by blasting during the construction of a municipal tunnel located in downtown area of city of Amoy is described. Longitudinal vibration velocity attenuation, vibration velocity distribution of cross section and vibration near the excavation face are presented. In addition it puts forward the permitted value of vibration velocity for various sort of surrounding rock around tunnel and the safety criteria for tunnel vibration.
