网格-弹簧(Lattice-Spring-Based)方法
1 网格-弹簧法
本文简要汇总了网格-弹簧方法(lattice-spring-based method)的部分最近文献。这不是一个文献回顾，只是使用机器学习方法从我们的岩土工程大数据集中抽取出相关内容。
网格-弹簧法LS(lattice-spring-based method)最先由Cundall and Damjanac (2009)提出，并在Itasca内部开发(没有商业发布)了一个相应的软件称之为Slope Model, 用来分析脆性断裂的岩体边坡稳定性。之后主要由加拿大的一些大学包括UBC, University of Alberta, SFU，Laurentian University的岩石力学研究人员以及Itasca公司自身继续扩展了这项研究。
LS的核心算法是PFC，它将PFC模型中的颗粒用节点代替，用弹簧表示键与键之间的接触，完整的岩石断裂用弹簧的断裂来表示。通过创建一个合成岩体模型SRM, 允许节理滑动和张开以及完整岩石的断裂。这种分析方法从用户指定的DFN得出的节理形状，然后对节理网络内的非稳态流体流动和压力进行模拟，地下水可以在节理和岩石中流动，当新的裂缝形成时，流动网络也会自动扩展。
