The present invention proposes a test device and test method for the load-bearing deformation of an air bag ring for landslide escape, wherein the device includes a bottom plate, a side plate, a rotating shaft, a formation horizontal reaction force spring, a pressure plate, a jack, a jack reaction force plate and a reaction force rod. The bottom plate is used to place the inflated landslide escape air bag ring, and the two side plates are respectively connected to both ends of the bottom plate through the rotating shaft to clamp the air bag ring; the formation horizontal reaction force spring is connected between the two side plates; The pressure plate, the jack and the jack reaction plate are sequentially placed on the top of the airbag ring from bottom to top; the jack reaction plate is fixedly connected to the bottom plate through the reaction rod. The load-bearing deformation testing device of the present invention is simple in structure, cheap in price, convenient to dismantle, and can be reused; the device has a high degree of simulation, and the stress state of the airbag ring test is close to the actual stress state. The load-bearing deformation test method of the invention has good standardization, and the stiffness coefficient of the stratum horizontal reaction force spring can be directly calculated through the geological survey report.
Description
technical field [0001] The invention belongs to the technical field of underground engineering emergency repair equipment testing, and in particular relates to a testing device and testing method for bearing deformation of a landslide escape airbag ring. Background technique [0002] Tunnel collapse is a great threat to people's lives. At present, the methods of landslide rescue include external rescue and internal self-rescue. [0003] The external rescue basically adopts the following methods: first, use measures such as pipe sheds, small ahead conduits, surface grouting or freezing methods to reinforce the collapsed and broken areas to prevent further development, and then use partial excavation methods to clean up the collapsed bodies. Due to the extremely poor stability of the surrounding rock in the landslide area, grouting pre-reinforcement or pre-support is required when dealing with the landslide. However, whether it is pre-grouting or pre-support, it is a secondar...
