摘要
目前,很多轨道交通工程都建设在岩溶地段隧道,而位于底部的溶洞因为充填物比较松软,所以隧道基底施工难度较大。在有些地区的溶洞岩质不坚固,有较多的破碎物,如果施工中存在问题,就容易发生坍塌现象。而且溶洞构造复杂,施工中可能遇到水囊使得岩石、泥土大量冲向隧道,所以必须有效把握爆破施工技术。
Nowadays,many rail transit projects are built in Karst tunnels,and the karst caves at the bottom are difficult to construct because of the soft fillings. In some areas,the karst cave is not strong and has more broken materials. If there are problems in construction,it is easy to collapse. Moreover,the structure of karst cave is complex,and water bags may be encountered in the construction,which may cause a large number of rocks and soil to rush into the tunnel,so we must effectively grasp the blasting construction technology.
