Acquisition of a Servo-Controlled Bi-axial Test System for Geomechanics and Structural Engineering Applications

9521686帕拉克-诺尔特圣母大学土木工程与地质科学系由于其跨学科性质，非常适合开发一个独特的项目来调查国家基础设施的地质力学和结构组成部分。收购一家最先进的测试设施将以综合的方式放大我们努力的推力。这项提议的目的是获得一种具有静、动态加载能力的伺服控制双轴液压试验系统，以创建一个可用于测试：(1)受循环和动态载荷的结构部件；(2)受模拟浅层地壳应力的岩石和土壤的响应，即在工程现场或采矿或废物隔离深度遇到的应力。工程结构构件受垂直作动器的法向载荷作用时，可以施加水平位移的动力作动器模拟工程结构构件的地震情况。***

9521686 Pyrak-Nolte The Department of Civil Engineering and Geological Sciences at the University of Notre Dame is ideally suited for developing a unique program to investigate the geomechanical and structural components for the nation's infrastructure because of its interdisciplinary nature. The acquisition of a state-of-the art test facility will amplify the thrust of our effort in an integrated manner. The objective of this proposal is to acquire a servo-controlled bi-axial hydraulic test system with both static and dynamic loading capabilities to create a system that can be used to test: () structural components subjected to cyclic and dynamic loads; and (2) the response of rocks and soils subjected simulated shallow crustal stresses, i.e. stresses encountered at engineering sites or at mining or waste isolation depths. Earthquake conditions on engineering structural components will be simulated with dynamic actuators that can apply horizontal displacements while the components are subjected to normal loads from the vertical actuator. ***
