Laboratory wave generator for studying wave impacts on retaining walls

需要一个造波机(造波机)和相关软件。该系统包括：在水槽上游端产生波浪的活塞和桨；安装在桨内和沿水槽测量波高的波动计；以及控制硬件和软件。所需的设备将支持两个研究轴线：1)调查波浪对挡土墙的影响；以及2)动载引起的挡土墙行为。研究轴线1专注于波浪冲击挡土墙(海堤)的物理和数值实验。造波机将用于对优化的挡土墙几何形状进行物理实验，并为数值解产生必要的验证数据。研究轴线2重点研究动侧向土压力系数的确定。动态荷载将通过水波施加在仪表式挡土墙上，这将允许确定这些系数。*对于研究界来说，拟议的研究结果将为优化受波浪影响的挡土墙提供创新方法，并提供急需的动侧向土压力系数。对于更大的社区来说，结果将对管理加拿大海岸线基础设施的市政当局和政府组织大有裨益。例如，魁北克交通部一直存在与沿海公路侵蚀有关的问题，并已确定34公里的公路有即将受到侵蚀的危险。由于气候变化，交通部预测，到2100年，将有100多公里的道路因海岸侵蚀而暴露出来。由所要求的造波机实现的研究活动的结果将直接导致挡土墙几何形状的优化，从而减轻波浪作用的侵蚀影响。因此，这一结果将为加拿大和其他地方带来巨大的货币和公共安全利益。**

A wave generator (wavemaker) and associated software are requested. The system consists of: a piston and paddle to generate the waves at the upstream end of the flume; wave gauges installed in the paddle and along the flume to measure wave height; and controlling hardware and software. Two research axes will be supported by the requested equipment: 1) investigation of wave impacts on retaining walls; and 2) retaining wall behaviour induced by dynamic loads. Research Axis 1 focusses on both physical and numerical experiments involving wave impacts on retaining walls (seawalls). The wavemaker will be used to perform physical experiments on optimized retaining wall geometries and produce essential validation data for the numerical solutions. Research Axis 2 focusses on the determination of dynamic lateral earth pressure coefficients. Dynamic loads will be applied by water waves on the instrumented retaining wall, which will allow for the determination of these coefficients.******For the research community, the results of the proposed research will provide innovative methods for optimizing retaining walls affected by waves, as well as, providing much needed dynamic lateral earth pressure coefficients. For the greater community, the results will be of great benefit for municipalities and governmental organizations who manage infrastructure on Canada's coastlines. For example, the Quebec Ministry of Transport has ongoing problems associated with coastal erosion of roads and has identified 34 km of roads that are in imminent danger of erosion. Due to climate change, the Ministry predicts that by the year 2100, over one hundred km of roads will be exposed due to costal erosion. The outcomes from the research activities enabled by the requested wavemaker, will directly lead to optimized retaining wall geometries, which will mitigate the erosive effects of wave action. Thus, the outcomes will have great monetary and public safety benefits for Canada and elsewhere. **
