Hard soils and soft rocks are transitional materials that have properties evolving from soft rock to soft soil. They are widespread in Australia and typical examples include mudstone, claystones, shales and tuffs. These materials are very difficult to handle, mainly due to the fact that their strength, stiffness and volume can change substantially in response to environmental actions such as cyclic wetting and drying. Proper prediction of the transitional behaviour of these materials is crucially important for analysing the stability and serviceability of civil structures founded on them. This project aims to develop a theoretical and practical framework for characterising the transitional behaviour of hard soils and soft rocks.

硬土和软岩是由软岩性质向软土性质演化的过渡性材料。它们在澳大利亚广泛分布，典型的例子包括泥岩、粘土岩、页岩和凝灰岩。这些材料非常难以处理，主要是因为它们的强度、刚度和体积会随着循环湿润和干燥等环境作用而发生显着变化。这些材料的过渡行为的正确预测是至关重要的，以分析基于它们的土木结构的稳定性和可用性。该项目旨在开发一个理论和实践框架，用于表征硬土和软岩的过渡特性。
