Parallel Processor Computation and Stability of Openings in Jointed Rock

本研究的目的是建立一种计算方法来评估节理岩体中地下设施在不同类型突变荷载作用下的安全性。该模型将基于三维可变形块，其中岩石由可变形元素表示，节理由界面表示。该模型将包括循环变形过程中伸缩节理行为和粗糙性退化的模型。这些模型将通过显式集成及时集成。计算机程序将在大规模并行计算机上实现，以便在合理的计算时间内解决现实的三维模型。

The objective of this research is to develop a computational method for assessing the safety of underground facilities in jointed rock under various types of catastrophic loads. The model will be based on three dimensional deformable blocks in which the rock is represented by deformable elements and the joints are represented by interfaces. Models for dilatory joint behavior and asperity degradation during cyclic deformation will be included in the model. The models will be integrated in time by explicit integration. The computer program will be implemented on massively parallel computers so that realistic three dimensional models can be solved in a reasonable amount of computation time.
