This project aims to establish a rational predictive capability for the responses of concrete gravity dams subject to extreme design earthquakes. This will include the development of innovative numerical methods for effective modelling of crack propagation and closure, large slips on crack faces and weak interfaces, dam-reservoir interaction, dam-foundation interaction and automatic mesh generation. The expected outcomes of the project will be a significantly improved prediction tool. It is also anticipated that the project will result in improvements in dam and public safety, and more efficient use of funds for dam safety upgrades and management.

本计画旨在建立混凝土重力坝在极端设计地震作用下反应之合理预测能力。这将包括开发创新的数值方法，用于裂缝扩展和闭合、裂缝面和弱界面上的大滑动、大坝与水库的相互作用、大坝与地基的相互作用和自动网格生成的有效建模。该项目的预期成果将是一个大大改进的预测工具。预计该项目还将改善大坝和公共安全，并更有效地利用资金进行大坝安全升级和管理。
