Supporting structure of active fault crossing hydraulic tunnel
The invention belongs to the technical field of tunnel engineering, and discloses a supporting structure of an active fault crossing hydraulic tunnel, which comprises a plurality of linings and a plurality of water stopping devices which are sequentially and fixedly arranged along the circumferential direction or the axial direction of the inner wall of the hydraulic tunnel; one end of each lining is provided with a guide groove, and the other end of each lining is provided with a bolt hole; the adjacent linings are arranged in a lap joint mode, the bolt holes of the adjacent linings coincide with the guide grooves and are connected through bolts, and the length of the guide grooves is larger than the diameter of screw rods of the bolts. The water stopping devices are arranged in the lap joint areas of the adjacent linings. When slight fault dislocation occurs, the lining cannot be damaged due to the fact that dislocation allowance is reserved in the guide groove of the supporting structure, and normal operation of the hydraulic tunnel can be guaranteed. When the lining is damaged due to serious fault movement, only the lining at the damaged position is replaced, construction can be completed through lap joint between the linings, and construction is convenient and fast.
本发明属于隧洞工程技术领域，公开了一种跨活断层水工隧洞的支护结构，包括沿水工隧洞内壁周向或轴向依次固定设置的多片衬砌和多个止水装置；每片衬砌的一端设置有导向槽，另一端开设有栓孔；相邻衬砌搭接设置，且相邻衬砌的栓孔与导向槽重合，并通过螺栓连接，导向槽的长度大于螺栓的螺杆的直径；止水装置设置于相邻衬砌的搭接区域。在发生轻微断层错动时，本发明的支护结构因导向槽留有错动余量，因此衬砌不会被破坏，能够保证水工隧洞的正常运行。当发生严重一些的断层错动导致衬砌损坏时，可仅更换破坏处的衬砌，通过衬砌之间的搭接就可完成施工，施工方便、快捷。
