The invention discloses a toughness structure for a plate mobile belt tunnel. The structure comprises a yielding type anchor rod, a preliminary spraying concrete layer, a reinforcing mesh, a circularhole type honeycomb H-shaped steel arch frame, a hinge, a slidable steel sleeve, a waterproof layer, a honeycomb steel box prefabricated module joint, a honeycomb cooling hole, secondary lining concrete, a rubber strip, a steel box prefabricated module top sliding groove, a steel box prefabricated module top rotating disc clamping base, a multifunctional structure health monitoring sensing component and a lifting ring. Due to the active protecting and energy releasing effects of the yielding type anchor rod and the compressible deformation energy absorption effect of the honeycomb steel box prefabricated module joint, the functions of releasing partial surrounding rock pressure and deformation energy and absorbing seismic dynamic load effect accumulation energy are achieved jointly, then,the safety coefficient of the tunnel structure is increased, later recovery can be actively responded to and facilitated when an earthquake happens, and the good anti-seismic toughness is achieved.
Description
technical field [0001] The invention relates to the fields of tunnel engineering, engineering anti-seismic, disaster prevention and mitigation, and in particular to a tough structure used for tunnels in active plate zones. Background technique [0002] At present, many projects of great strategic significance are being carried out on the edge and depth of the Qinghai-Tibet Plateau in my country. Among them, the Sichuan-Tibet Railway is one of the important railway lines being planned and constructed in my country. The railway line spans the Yangtze Plate, the Sichuan-Yunnan Block, and the Qiangtang Under the background of complex geological structure, active faults, earthquakes and geological disasters are extremely developed along the Sichuan-Tibet Railway, which severely restricts the planning and construction of the Sichuan-Tibet Railway. The tectonic stress field and geothermal field along the Sichuan-Tibet Railway are complex. During the construction of deep-buried tunne...
