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.

本研究的目的是开发一种计算 地下设施安全评价方法 在各种类型的灾难性载荷下的节理岩石。模型 将基于三维可变形块， 岩石用可变形单元表示，节理 由接口表示。关节活动迟缓的模型， 将包括循环变形过程中的粗糙度退化 中。这些模型将通过显式的 一体化计算机程序将在 大规模并行计算机， 模型可以在合理的计算时间内求解。
