摘要
淤泥质软土在动态载荷作用下具有黏弹塑性流变力学特性。在理论分析和测试基础上,建立了黏弹塑性流变力学模型,并推导了新的流变方程和动态黏弹性流变参数。研究结论对分析动态载荷作用下软土流变力学响应与稳定性,探索软土加速流变并导致岩土地质灾害的动力学机制等具有重要的理论意义,对维护岩土工程的安全性等具有重要的工程意义。
The theoretical analysis and test indicate that sullage soft soil has viscoelasto-plastic theological characteristics under dynamic loading. Based on this, the viscoelasto-plastic theological model is established, and a new rheological equation and dynamic rheological parameters are deduced. The research conclusions have important theoretical significance for us to analyze rheological dynamic response and stability, theology dynamic mechanism of leading geological disaster, and also for us to keep geotechnical engineering security.
