9521686 Pyrak-Nolte 圣母大学土木工程和地质科学系因其跨学科性质，非常适合开发独特的项目来研究国家基础设施的地质力学和结构部件。 收购最先进的测试设施将以综合方式增强我们努力的推动力。 本提案的目的是获得一个具有静态和动态加载能力的伺服控制双轴液压测试系统，以创建一个可用于测试：（）承受循环和动态负载的结构部件； (2) 岩石和土壤在模拟浅层地应力下的响应，即在工程现场或采矿或废物隔离深度遇到的应力。 工程结构部件的地震条件将通过动态执行器进行模拟，动态执行器可以施加水平位移，同时部件承受垂直执行器的法向载荷。 ***

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. ***
