Parallel Processor Computation and Stability of Openings in Jointed Rock

本研究的目的是发展一种评估节理岩层地下设施在不同类型灾害性荷载作用下的安全性的计算方法。该模型将基于三维可变形块体，其中岩石由可变形单元表示，节理由界面表示。模型中将包括循环变形过程中的伸缩关节行为和粗糙度退化模型。模型将通过显式积分的方式进行及时的积分。该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求解真实的三维模型。

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.
