The research on dynamic rheological mechanical response and rheological dynamic model of geological disaster of soft rock-soil
摘要
The practice and theoretic analysis indicate that the dynamic loading(such as earthquake, tsunami, raging billow, vibration)are the important factor and mainly power of inducing geological disaster of soft rock-soil. The objective factors (such as climate and weather, Geotechnical Engineering and geological terms, landform and physiognomy, the disturbness of building project) and inducing power of bursting out geological disaster in our country are analyzed and summarized. The research countermeasure of theological dynamics of geological disaster of soft rock-soil is put forward, the research clue and potential application are discussed. The theological mechanics response and theological parameters of soft rock-soil are tested and analyzed under dynamic loading, the viscoelastic-plasticity theological dynamic model is established, and new theological equation is deduced. The research results settle better foundation for us to research deeply critical mechanics terms of bursting out geological disaster and dynamic key indexes of forecast geological disaster. All these have important theory and actual signification for us to reveal the theological dynamic mechanism of bursting out Geotechnical Engineering and geological disaster under dynamic loading, perfect the monitoring theory of disaster, improve the science and veracity of forecasting.
