Structural Strength Evolution of Soil under Dynamic Load

Abstract:

The present paper gives a detailed inferential reasoning to a new mathematical model for structural strength indicator of soil under dynamic load, which is established on the base of law of conservation of energy and strain energy transformed principle. Through dynamic triaxial test, it points out that the relation of principal stress difference and accumulation subsidence quantity exists threshold value and calculates the structural strength indicator change rule. According to the analysis of structural strength indicator variation rule, it lays emphasis on uniformity of structural strength indicator variation rule under different vibration times and draws the conclusion which is the increasing of the structural strength indicator.
