【摘要】：隧道施工期突水具有普遍性、突发性和灾害严重性等特点,为隧道工程界所广泛关注。文章基于以往隧道施工突水灾害与引发突水灾害的不良地质体之间的关系,总结提出了包括充水(泥水混合充填)岩溶、未胶结富水压性断层强烈挤压破碎带、未胶结富水张性断层、地下向斜蓄水构造、富水顺层错动(节理密集发育岩体)破碎带和充水废弃矿巷等6种可能导致隧道施工突水灾害发生的突水致灾构造;根据突水致灾构造构成、可能的隔水岩土盘类型和工程处理措施适宜性,提出了突水致灾构造分类的三项原则,将突水致灾构造划分成完全充水体构造和裂隙空隙/孔隙含水体构造,并提出了相应工程处理措施。
[Abstract]:The water inrush during tunnel construction is universal, sudden and serious. Based on the relationship between the water inrush disaster of tunnel construction and the bad geological body which caused the water inrush disaster in the past, this paper summarizes and puts forward the karst which includes water filling (mixed filling with mud and water). The uncemented water-pressure faults are strongly crushed and broken, the uncemented water-rich and tensional faults are uncemented, and the underground syncline water storage structures. There are 6 kinds of water-inrush structures which may lead to water inrush disaster in tunnel construction, such as fracture zone and abandoned mine roadway with water filling in the fractured zone (joint-dense developed rock mass) in Fushuishun formation. According to the composition of water-inrush structure, the possible type of water-isolating rock and soil plate and the suitability of engineering treatment measures, three principles for classification of water-inrush disaster-causing structures are put forward. The structure caused by water inrush is divided into completely filled water structure and fissure void / pore containing water structure, and the corresponding engineering treatment measures are put forward.
