A novel foundation system is proposed to support sound walls (also known as noise barriers or acoustical barriers). It is designed**to support the complex loading system involving small axial load but large lateral load and bending moment. Sound walls are**utilized for mitigation of ambient noise due to traffic or industrial and commercial activities. They are conventionally supported by**drilled shafts, but Atlantic Industries Limited is seeking foundation systems that provide enhanced lateral capacity, cost-savings,**and fast installation and utilization. Standard Steel H piles can meet the requirements for efficient installation, but lack the required**lateral stiffness to adequately support sound walls. Working with Dr. Naggar at UWO, Atlantic Industries Ltd will investigate**alternative methodologies to increase the lateral capacity of the sound wall foundation while reducing the installation time. The**testing program undertaken in the proposed study will assess the performance of the proposed foundation systems and help**develop design guidelines for the implementation of the proposed foundation system in sound walls construction.

提出了一种新型的基础体系来支撑声墙(也称为声屏障或声屏障)。它的设计目的是**支持复杂的加载系统，包括小的轴向载荷，但大的横向载荷和弯矩。声墙**用于缓解交通或工商业活动引起的环境噪音。它们传统上由**钻孔支撑，但大西洋工业有限公司正在寻求能够提供增强的横向能力、节省成本**和快速安装和使用的基础系统。标准的H型钢桩可以满足高效安装的要求，但缺乏所需的**侧向刚度来充分支撑隔音墙。大西洋工业有限公司将与UWO的Naggar博士合作，研究**在减少安装时间的同时增加声墙基础横向容量的替代方法。在拟议的研究中进行的**测试计划将评估拟议的基础系统的性能，并帮助**制定在声墙施工中实施拟议的基础系统的设计指南。
