The effects of cyclic loading on partially saturated soils

本项目旨在预测地基上部部分饱和层在循环荷载作用下的沉降和强度。我们的大多数关键基础设施都建在这一层上，但目前我们还不能可靠地预测部分饱和土壤对地震、交通和建筑过程中产生的循环荷载的地面反应。该项目预计将开发一个新的数值模型，可以预测循环荷载的影响，并提供更新的工程指导，以确保依赖于部分饱和土壤的基础设施的完整性。该项目所涉及的过程的改进预测将具有显著的经济效益，同时确保基础设施的安全性和安全性，并降低维护成本。

This project aims to predict the settlement and strength of the upper, partially saturated layer of the ground when it is subjected to cyclic loading. Most of our critical infrastructure is built on or in this layer, but currently we cannot reliably predict the ground response of partially saturated soils to the cyclic loads that arise from earthquakes, traffic and construction processes. The project is expected to develop a new numerical model that can predict the effects of cyclic loads, and provide updated engineering guidance to ensure the integrity of infrastructure dependent on partially-saturated soils. Improved predictions of the processes involved resulting from this project will have significant economic benefits, as well as ensuring the safety and security of infrastructure and reduced maintenance costs.
