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.

该项目旨在为受到极端设计地震的混凝土重力大坝的反应建立合理的预测能力。这将包括开发创新的数值方法，用于有效建模裂纹繁殖和闭合，裂纹面上的大滑板和弱接口，坝 - 水塞的相互作用，大坝 - 发现相互作用和自动网格产生。该项目的预期结果将是一个显着改进的预测工具。还可以预料，该项目将改善大坝和公共安全，并更有效地利用资金来进行大坝安全升级和管理。
