The invention discloses a waste tennis ball composite cushion layer structure suitable for a shed tunnel project and a design method thereof. According to the waste tennis ball composite cushion layerstructure suitable for the shed tunnel project, by using a waste tennis ball, a buffering cushion layer is constructed so that the material can sufficiently develop a buffering and energy consuming effect under the impact effect to effectively reduce the impact force, and therefore, the safety of a shed tunnel structure under the action of boulder dash load is guaranteed; and compared with a traditional sand cushion layer, the waste tennis ball composite cushion layer can enhance the boulder resisting ability of a shed tunnel by 2-3 times in the case of substantially same impact load. Meanwhile, as the waste tennis ball contains heavy metal and harmful substances, and the waste tennis ball is used as the buffering cushion layer, the engineering cost can be reduced, and moreover, the secondary utilization of the waste tennis ball can be realized, resource consumption is reduced, the environment pollution problem is solved, the waste tennis ball composite cushion layer structure suitable for the shed tunnel project is suitable for requirements on sustainable development, and better social, environment and economic benefits are realized.
Description
technical field [0001] The invention relates to the technical field of prevention and control of landslides and rolling stones, in particular to a composite cushion structure of waste and old tennis balls suitable for shed tunnel engineering and a design method thereof. Background technique [0002] Rolling stone disasters are characterized by suddenness, poor predictability, fast speed, high energy, long moving distance, large impact range, difficult monitoring and early warning, and serious hazards. The prevention and control methods of rolling stone disasters can usually be divided into two categories: active protection measures and passive protection measures. Active measures are difficult to be effective due to geographical location, and shed holes in passive engineering are a very effective method. Traditional reinforced concrete shed holes The structure itself is protected from rolling stones by backfilling its top with a thick layer of sand. [0003] At home and abr...
