细观颗粒流方法是研究岩土大变形的重要工具,运用该方法的关键是通过伺服令颗粒体系满足一致性条件,赋予参数后得到想要的宏观性质。针对不规则模型等无法采用常规刚性伺服情况,提出了一种细观颗粒体系自适应伺服方法,案例验证表明,该方法不仅可以让颗粒体系各处均接近伺服应力,误差小于10%,且不需要改变模型边界墙的位置,保证了颗粒流数值模型状态控制的精确性,可以准确反映岩土材料的力学性质。以某软岩高边坡为例,研究成果可为解决具体工程边界的细观颗粒流模型构建提供参考。
- Abstract:
-
Mesoscopic particle flow method is an important tool to study the large deformation of rock and soil. The key to using this method is to make the particle system satisfy the consistency condition through servo, so that the desired macroscopic properties can be obtained after parameter assignment. Aiming at the situation where the conventional rigid servo cannot be applied to irregular models and the like, an adaptive servo method for the mesoscopic particle system is proposed. Case verification shows that this method can not only make the particle system approach the servo stress everywhere, with an error less than 10%, but also does not require changing the position of the model boundary wall, ensuring the accuracy of the state control of the particle flow numerical model and accurately reflecting the mechanical properties of geotechnical materials. Taking a certain high soft rock slope as an example, the research results serve as an important reference for constructing the mesoscopic particle flow model of specific engineering boundaries.
