摘要
草峪岭隧洞是引沁入汾工程的总干线 ,全长 1 9 4km。该洞穿越的地层岩性复杂。在隧洞开挖中 ,采用新奥法施工 ,即根据不同的地质条件 ,设计制定不同的光面爆破施工方法和爆破参数 ,并依据施工监测获得的数据随时修正技术参数。从而减少了塌方和超挖 。
The smooth blasting is applied in the NATM excavation of Caoyuling tunnel,Shanxi.The construction method and parameters of the blasting are determined according to the properties of the surrounding rock and the parameters are modified according to the information obtained in the construction at any time,the cavein,the overbreak,and the corresponding investment of the tunnel thereby were decreased.
