| It is essential on the geotechnological function while calculating that the soil body loads the relation between a literary composition of motive force of stress emergency under function in vibration. Among the actual project, deformation, soil of body very complicated, it is apt to make soil body take place creep , stress lax , elastic aftereffect ,etc. rheology characteristic than quiet year for power to load. The power rheology characteristic of the soil body will lead to the fact it is out of shape and subsiding that the building or the machine foundation happen within short time when loaded by vibration, the harm to the road bed and bridge that are loaded by vibration for a long time is more serious. Under many circumstances, the soil body is received for a long time after gravity or other quiet strength function consolidation are finished, when moved the function of loading, it is out of shape that still happen, in order to consider this part is out of shape, need to carry on the rheology analysis of motive force.This paper has carried on preliminary analysis and discussion to the rock soil medium rheology mechanics model theory, utilize Laplace transforms to establish constitutive equations of setting up four kinds of linear viscoplasticity models, and derive the corresponding creep equation and relax the equation in view of the above. Have derived the result and analysed the soil body loads the rheology characteristic under the terms in the quiet strength and motive force according to the theory, probe into the rheology parameter of motive force and dependence of the quiet strength rheology parameter. Have loaded the rheology mechanics characteristic which made the soil body in moving and summarized and analysed systematically, explore that realizes the stress emergency relation that exerts different vibration with the preliminary research soil body while loading the form . According to glueing the model theory of the elastomer linearly , move three axles to test in the room, is it obtain the experience formula after fitting to put actual soil experimental curve of kind through equivalent linear mathematics means test data in order, try to get to move mould compared with damping , experience theory formula fit law and survey result to be identical and better different condition. This paper still utilizes motive force to load and make and glue the rheology characteristic of the elastomer finally, set up the vibration models of top structure and viscoplasticity soil with interactive body, utilize this model to carry on vibration analysis , has summarized the damping... |
