Experimental Research On Lateral Sliding Of Pressing Process Of Rock Plate With Oblique Fault

The thesis is based on oblique fault rock plate,and explore the test law of the pressing process of oblique fault rock plate.Using four different speed simulate four different periods of the day,the data mainly includes vertical displacement,vertical force,lateral displacement and lateral force curve changing with time.through the analysis of time-experiment force-displacement curve and experiment force-displacement curve,explore the test law of pressing process of oblique fault rock plate.Building complete simulation test system.According to micro mechanical press can provide the vertical force,lateral force,bolt can provide pressing force,and spring can provide restoring force,which simulate all directions of force suffered by the plate motion.Through different vertical loading speed simulate different vertical pressing pressure.Finishing all the parts through drawing test system frame and part drawing by Autocad software.In this way we can assemble a whole experimental mechanism to simulate interaction of plates.Through the experiment of the pressing to oblique fault rock plate and produce lateral sliding.Via analysis and processing,we can acquire time-experiment force-displacement curve and experiment force-displacement curve.Thus summarize the law of olique fault rock plate generate lateral sliding in the diffdrent loading speed.The experimental results show that in the process of vertical loads,the larger vertical load we imposed,the larger vertical force and sideslip displacement we acquire in the whole loading process.At the same time,the smaller vertical load we imposed,the smaller vertical force and sideslip displacement we acquire.Further more,the larger vertical load we imposed,the smaller deformation modulus we acquire.In the begining of lateral loading,the deformation modulus remain unchanged.After a period of time,the deformation modulus increse all of sudden and last for some time.Then the deformation modulus decerese as the first phase.At last,the Transverse force-displacement curve show the regular of flat at first,then steep,flat at last.
