Description
Technical field
The utility model relates to a kind of true three axle rock burst physical simulation experiment systems for deep-lying tunnel, belongs to Geotechnical Engineering field.
Background technology
In order to adapt to the needs of Chinese national economy fast development, the strategy such as " west-to-east power transmission ", " south water to north " is implemented in succession, occur Deep-buried Long And Big tunnel (tunnel, the tunnel) engineering under large amount of complex geological conditions, it is rare that its project scale and technical difficulty are world institute thereupon.The tunnel of growing up of these high buried depths spreads all over the fields such as Hydraulic and Hydro-Power Engineering field, traffic engineering field, railway, highway field, mining engineering field and nuclear waste disposal, national defense construction, buried depth as maximum in Jinping hydropower station diversion tunnel reaches 2525 meters, and the mining depth of Failing In Hongtoushan, Dongguashan Copper Mine, Technology of Anqing etc. all approaches or surpassed 1000m.Can predict, the progressively deep along with China's Foundation Design construction and development of resources, will there will be increasing Deep-buried Long And Big tunnel (tunnel, tunnel) engineering.Increase along with buried depth, geostatic stress obviously increases, the high strength rock burst that the off-load of deep-lying tunnel excavation is brought out takes place frequently, and cause a tremendous loss of lives, mechanical failure, construction delay and heavy economic losses, and the harmfulness of this disaster enlarges markedly along with the increase of buried depth and stress level.Therefore, rock burst hazard has become the bottleneck problem that restriction deep-lying tunnel (tunnel, tunnel) engineering safety is built, and the reasonable assessment of rockburst risk and Accurate Prediction have become the construction of deep-lying tunnel engineering safety and the engineering crucial difficult problem anxious to be resolved of preventing and reducing natural disasters.
Physical simulation experiment is to take the theory of similarity as basis, by model test piece loading, excavation, supporting to reduced scale, operate, the residing stress of primary rock state of the on-the-spot tunnel of model engineering, excavation and supporting etc., due to can be in test specimen pre-buried various monitoring original papers, can change easily loading environment and excavation condition, by monitoring device, obtain stress distribution and the deformation behaviour in test specimen, for the excavation construction of engineering site tunnel provides, instruct and use for reference, being therefore widely used in the research and construction of subsurface rock engineering (tunnel, tunnel etc.).Chinese scholars has been developed various true three axle geomechanics model experimental systems for different research purposes, is applied in the static(al) damage study of tunnel, as:
(1) Chinese Journal of Rock Mechanics and Engineering (2004, the 21st phase) has designed a kind of novel true three axle Roadway model testing counters, for studying the stability problem of colliery roadway surrounding rock, adopts flat jack to load six of test specimen faces.
(2) Chinese Journal of Rock Mechanics and Engineering is (2010, the 1st phase) designed large-scale geomechanics model test system under a kind of true triaxial load condition, the little bearing plate of the loading jack of each direction by is separately applied to test specimen surface by power and applies gradient load.
(3) geotechnical engineering journal is (2010, the 10th phase) designed a kind of high crustal stress genuine three-dimensional load model trial system for studying the zonal fracturing mechanism of roadway surrounding rock, each direction load capability of pilot system is 200 tons to the maximum, and sample dimensions is the square of 0.6 meter.
Rock burst is recurrent a kind of special power destruction in buried, heavily stressed rock mass, more current researchers study by carrying out the physical simulation experiment of rock burst under simple two-dimentional load mode or plane strain condition, the actual forced status of this and deep rock mass is not inconsistent, and deep rock mass many places are in three-dimensional stress; And often there is following problem during the physical simulation experiment that three conventional axle physical analog test apparatus carry out rock burst:
(1) load capability of part experimental facilities lower (as flexible pocket or flat jack loading), can not provide the enough large residing high-ground stress state of the buried rock mass of Load Simulation.
(2) due to the defect of charger (as the little bearing plate of each the little jack on each loading direction by separately transfers the load on test specimen), can make test specimen discontinuity, test specimen surface produces unnecessary shear stress, has affected accuracy and the reliability of experimental result.
(3) current disclosed three-dimensional physical simulation pilot system does not all have to reflect blast disturbance to excavating the sex device of shaping Stability of Tunnels or method, and in actual deep-lying tunnel excavation, adjacent tunnel drilling and blasting method excavation even plays control action to the considerable influence that has of the tunnel rock burst that is shaped.
Chinese patent application publication No. is CN102636386A, date of publication 2012.8.15, denomination of invention is " uniform-centralized loading system of large-tonnage ", this application case discloses a kind of mode of model test piece being carried out to heavy load, can make model test piece stressed evenly, but this loading system is only a kind of simple unidirectional loading system, and model test piece is stressed is that one dimension is stressed.
Along with the buried depth of subsurface rock engineering is increasing, rock burst hazard is more and more outstanding, due to complexity and the high requirement to device loads ability of experimental system, and the true three axle rock burst physical simulation experiment devices for deep-lying tunnel that current shortage is special.
