Abstract:The tunnel engineering of water conservancy and hydropower projects can reasonably plan water resources, alleviate water and energy shortages, but is limited by geological conditions and has certain construction hazards. Therefore, it is necessary to do a good job in tunnel lining and support reinforcement construction. The article takes the Xianghe Water Conservancy Hub and its supporting irrigation area project as an example to briefly explain the tunnel lining and support structure,and then explores in detail the key technologies for lining and shotcret-bolt support reinforcement construction, analyzes the stability of tunnel surrounding rock, verifies the effectiveness of construction technology.
