| 摘 要： | 隧道工程多深埋地下,工程地质、水文地质条件复杂。通过地表调查、隧道内开挖过程中的地质跟踪及多种物探仪器测试相结合等手段,以实测的各种数据为依据,对寨了隧道存在的隐伏地质灾害和围岩分级作出判定,适时地对原设计和施工工艺进行调整。并阐明和提出施工应重点关注洞内裂隙的溶蚀发育情况,判定隧道围岩为Ⅴ级,取得了良好效果。

| Abstract: | Tunnel engineering is often carried out in deep underground with complicated engineering geology and hydrogeology.Through surface investigation,geological tracking during tunnel excavation and geophysical instrument testing,the hidden geological hazard and surrounding rock classification of Zhailiao Tunnel are determined based on measured data to properly adjust the original design and construction technology.In addition,this paper describes and puts forward that corrosion development of inner fissure shall... |
