9521686 pyak - nolte圣母大学土木工程和地质科学系非常适合开发一个独特的项目来研究国家基础设施的地质力学和结构部件，因为它的跨学科性质。收购最先进的测试设备将以综合的方式扩大我们努力的推动力。本提案的目标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的系统：（）受循环和动态载荷的结构部件；(2)岩石和土壤在模拟浅层地应力下的响应，即在工程场地或采矿或废物隔离深度遇到的应力。工程结构构件的地震条件将用动态执行器来模拟，当构件受到垂直执行器的正常载荷时，动态执行器可以施加水平位移。＊＊＊

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. ***
