Expansive soils, highly sensitive to the environment, undergo dramatic strength and volume changes. This project aims to advance our understanding of expansive soils under different temperatures, hydraulic conditions, mechanical loads, and aqueous salinities. The project expects to use a combination of multidisciplinary knowledge, multiscale experiments and numerical simulations. The outcomes are a new multiscale model and advanced analysis/design tool for evaluating the performance of expansive soils under different conditions. The outcomes should provide the efficient way to mitigate the significant damage caused to infrastructure by expansive soils and facilitate the application of expansive soil products in waste disposal systems.

膨胀土是一种对环境高度敏感的土，其强度和体积变化剧烈。该项目旨在提高我们对膨胀土在不同温度、水力条件、机械荷载和水矿化度下的认识。该项目预计将使用多学科知识，多尺度实验和数值模拟的组合。研究结果为评价不同条件下膨胀土的性能提供了一种新的多尺度模型和先进的分析/设计工具。研究结果将为减轻膨胀土对基础设施的重大破坏提供有效途径，并促进膨胀土产品在废物处理系统中的应用。
