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. ***

9521686 PYRAK-NOLTE的公民工程和地质科学系的理想选择非常适合开发一个独特的计划，以研究该国基础设施的地质力学和结构组成部分，因为其跨学科性质。 获得最先进的测试设施将以综合方式扩大我们努力的作用。 该提案的目的是获得具有静态和动态负载能力的伺服控制的双轴液压测试系统，以创建可用于测试的系统：（）结构成分受环状和动态载荷约束； （2）岩石和土壤的反应受到模拟的浅层地壳应力，即工程地点或采矿或废物隔离深度所遇到的应力。 工程结构组件上的地震条件将使用动态执行器模拟，这些动态执行器可以施加水平位移，而该组件会受到垂直执行器的正常载荷。 ***
