饱和砂土中的地铁圆形衬砌隧道地震响应分析
|
摘要
研究目的:将多屈服面动本构模型引入土体动力有限元计算,在实际工程中,验证其正确性和合理性。研究结论:多屈服面动本构模型在描述土真实特性方面具有适用的普遍性和应用的灵活性;以往采用单屈服面模型进行计算是偏于安全的。
Research purposes: The purpose of bringing the multi-yield surface model into the soil mass dynamic finite element calculations is to verify its rationality and validity through the construction practice.Research conclusions:The multi-yield surface model has its popularity and flexibility to describe the characteristic of the soil mass and the previous calculation with the multi-yield surface model fovoured safety.
