This project will develop an innovative new method based on coupled finite element and scaled boundary finite-element analysis for predicting the ground vibrations induced by road traffic and underground or surface trains. The method will have immediate application in transportation engineering to predict traffic-induced ground vibrations, in geotechnical engineering to design isolation trenches and wave barriers to dissipate wave propagation, and in structural engineering to estimate in-structure vibration level and design isolators for sensitive equipment housed within. The technique will involve fundamental advances in the scaled boundary finite-element method, as calculations will be performed in a moving reference frame.

该项目将开发一种基于耦合有限元和比例边界有限元分析的创新方法，用于预测道路交通和地下或地面列车引起的地面振动。该方法将立即应用于交通工程，以预测交通引起的地面振动，在岩土工程设计隔离沟和波屏障消散波的传播，并在结构工程，以估计结构内的振动水平和设计隔离器的敏感设备内。该技术将涉及缩放边界有限元法的基本进展，因为计算将在移动参考系中进行。
