The aim of this project is to advance experimental, theoretical and computational bases for the mechanics of weak rocks, and provide scientists and engineers with much-needed predictive tools for quantitative evaluation and assessment of their behaviour in geological settings. Based on the theoretical results of the research, numerical algorithms will be developed that will assist engineers to apply the findings of the project to geotechnical engineering problems. By incorporating previously neglected aspects in the behaviour of weak rocks such as mechanical, environmental as well as cyclic loading degradation, confidence in the design methods will be increased to the point that costly over designs can be avoided.

该项目的目的是推进软弱岩石力学的实验、理论和计算基础，并为科学家和工程师提供急需的预测工具，以便对其在地质环境中的行为进行定量评价和评估。基于研究的理论结果，将开发数值算法，以帮助工程师将项目的结果应用于岩土工程问题。通过将以前被忽视的方面纳入软弱岩石的行为中，例如机械、环境以及循环载荷退化，设计方法的置信度将提高到可以避免昂贵的过度设计的程度。
