The objectives of the ongoing research program are the development of powerful design tools capable of solving practical engineering problems associated with medium-structure-wave interaction.   Three dimensional medium-structure-wave interaction analysis is a computationally intensive task, consequently it is desirable to develop efficient numerical procedures for application to engineering problems.     The proposed research is to extend and apply the numerical procedure outlined in [1]  to the following problems: i) the dynamic response of buried pipes in a seismic environment, ii) the dynamic response of submarine pipelines to nonlinear water waves and a seismic environment, iii) the dynamic response of layered viscoelastic medium.     The results of the work proposed here would represent a number of significant contributions.  The study on the dynamic response of buried  pipelines to seismic waves will provide important design information currently not available in the literature.The study on the dynamic response of buried submarine pipelines to water waves and earthquakes is of paramount importance in B.C. because of the proposal to construct a natural gas pipeline across Georgia Strait to Vancouver Island.   The results may be useful in the decision on whether to lift the moratorium on offshore drilling off the coast of B.C.     The combination of the above projects will lead to the long term goal which is the development of state of the art programs capable of solving practical engineering problems associated with dynamic medium-structure-wave systems.[1]Wegner, J.L., Yao, M.M., and Zhang, X., "Dynamic Wave-Soil-Structure Interaction Analysis in the Time Domain", International Journal of Computers and Structures", Vol. 83, Issue 27, pp. 2206-2214, 2005.

正在进行的研究计划的目标是开发强大的设计工具，能够解决与介质结构波相互作用相关的实际工程问题。   三维介质结构波相互作用分析是一项计算密集型任务，因此需要开发有效的数值程序以应用于工程问题。     拟议的研究是将[1]中概述的数值程序扩展到以下问题：i）地震环境中埋地管道的动态响应，ii）海底管道对非线性水波和地震环境的动态响应，iii）层状粘弹性介质的动态响应。     这里提出的工作结果将代表许多重大贡献。  关于埋地管道对地震波的动态响应的研究将提供目前文献中无法获得的重要设计信息。埋地海底管道对水波和地震的动态响应的研究在 BC 省至关重要。因为提议修建一条横跨乔治亚海峡到温哥华岛的天然气管道。   研究结果可能有助于决定是否取消 BC 省沿海海上钻探的暂停。     上述项目的结合将带来长期目标，即开发能够解决与动态介质结构-波浪系统相关的实际工程问题的最先进的程序。[1]Wegner, J.L., Yao, M.M., 和Zhang, X.，“时域中的动态波-土-结构相互作用分析”，国际计算机与结构杂志，第83卷，第27期，第17页。 2206-2214，2005 年。
