Waste Of Artificial Fill. Gold Heap City High Slope Dynamic Stability Studies

This paper primary research and achievements that concerned about the dynamic stability for Jindui city artificial filled relax high slope has been made as follow:(一) In the nature condition, utilizing Finite-element method and engineering geology technique, gained the type, mechanism, rule of the deformation and destruction of the slope as below: the type of unitary destroy; the shallow part destruction.(二) Using spectrum analysis investigate the transport character and primary rule of explosion wave in the medium, simulate the formula of attenuation for explosion wave, which will be used to guide the design of the engineering.(三) Under the dynamic load of the explosion, the numeric analysis has been done and achieve the rule as follow:(1) When the frequency of vibration is 0.3Hz, the acceleration of the slopes top gets the maximum; so 0.3Hz is believed the natural frequency of the slope as a whole;(2) The vibration of explosion can been magnified because of the condition of the landform, when the relative altitude is up to 45m, the acceleration of horizon gets the maximum; when the relative altitude is up to 100m, the absolute value of acceleration and the deformation of horizon is larger than that in the bottom of the slope;(3) In the period of forced vibration, at the top of the slope, the acceleration of horizon become larger and larger; at the middle part of the slope ,it becomes smaller;(4)When the explosion velocity of is much little, the shallow part destruction is the primary deformation of the slope .
