摘　　要：伴随城市地下空间的不断开发,在建造城市地铁隧道时,相邻隧道距离较近甚至超小间距相邻的问题会渐渐凸显。本章针对一超小间距隧道爆破开挖过程中的振速速度的测试,进行爆破方案的改进,保证了相邻隧道安全。With the continuous development of urban underground space, when constructing urban subway tunnels, the problem that the distance between adjacent tunnels is relatively close or even ultra-small distance between adjacent tunnels will gradually become prominent. In this chapter, aiming at the test of vibration velocity in the process of blasting excavation of a super small spacing tunnel, the blasting scheme is improved to ensure the safety of adjacent tunnels.
