地震荷载作用下冻土的动力学参数试验研究

LABORATORY STUDY ON DYNAMICS PARAMETERS OF FROZEN SOIL UNDER SEISMIC DYNAMIC LOADING

摘要:

基于地震动荷载作用下冻土的动三轴试验,定量研究了重塑冻结兰州黄土的动本构模型、动弹性模量在不同温度(-2℃、-5℃、-7℃、-10℃)下的变化规律,建立了相应的温度影响模型,为寒区建设工程提供了较为可靠的抗震设计依据.

Abstract:

A systematic dynamic characteristics of frozen soil under seismic loading is studied by means of dynamic triaxial tests. It involves dynamic constitutive model, dynamic elestic modulus in different temperatures of -2℃、-5℃、-7℃、-10℃. The model of dynamic parameters for the effect of low-temperature is established.
