建筑材料在高静态和动态下的行为 应力和高温下是非常重要的分析 资源开采和处置设施的设计 但在传统的结构中也是如此。 基本知识 这种材料行为是不完整的，主要是由于缺乏 实验 建议的高压三轴设备将 使这种实验研究成为可能。 三轴仪是 设计用于轴向压缩应力和围压， 至50000 psi和高达10000 psi的真实轴向拉伸应力。 的 电池将由当地一家专门从事高压 设备，而其他设备将由这家公司和麻省理工学院建造 工作人员和学生。 使用该仪器进行的研究 包括对岩石和混凝土的调查，这需要 中等试样尺寸、大载荷和动载荷、孔隙 压力和高温。

Behavior of construction materials under high static and dynamic stresses and under high temperatures is very important for the analysis and design of facilities in the resource extraction and disposal domain, but also in more conventional structures. Basic knowledge on such material behavior is incomplete largely due to a lack of experimentation. The proposed high pressure triaxial equipment will make such experimental research possible. The triaxial apparatus is designed for axial compression stresses and confining pressures of up to 50000 psi and true axial tensile stress of up to 10000 psi. The cell will be built by a local firm specializing in high pressure equipment, while the other equipment will be built by this firm and MIT staff and students. Research to be performed with this apparatus includes investigations on rock and concrete, which requires the combination of medium specimen size, large and dynamic loads, pore pressures and high temperatures.
