1引言目前,国内外在软土或浅埋条件下进行的隧道施工,不乏成功案例,但在两者同时具备条件下采用钻爆法穿越地面建筑物的施工却极少见。能够安全顺利通过并保证地面建筑不受影响,必须解决合理的开挖方法、控制爆破、超前 1 Introduction At present, there are many successful cases of tunnel construction at home and abroad under soft or shallow conditions. However, it is very rare to use the drilling and blasting method to penetrate the ground structures under the conditions of both. To be able to safely and successfully pass and ensure that the ground construction is not affected, we must solve the reasonable method of excavation, blast control, advanced
