A plane strain laboratory test apparatus will be constructed and used to quantify the non-linear mechanical properties of soils used in a wide range of geotechnical applications. These applications include reinforced soil walls and slopes, landslides, buried pipes, box culverts and deep underground storage. A plane strain test apparatus is required so that the soil properties correspond to the plane strain boundary conditions that prevail for many of these structures in the field. The apparatus will include the ability to test transparent soil to directly observe soil deformations and shear band development within the test specimen. The apparatus will also have unsaturated soil and cyclic testing capabilities. The soil properties will then be available to develop advanced numerical models to investigate these geotechnical applications under both static and earthquake loading conditions.

将建造一个平面应变实验室试验装置，用于量化广泛的岩土工程应用中使用的土壤的非线性力学性能。这些应用包括加固土墙和斜坡、滑坡、埋管、箱涵和深层地下储存。需要一个平面应变测试装置，以便土壤特性对应于现场许多此类结构普遍存在的平面应变边界条件。该设备将包括测试透明土壤的能力，以直接观察土壤变形和试样内剪切带的发展。该设备还将具有非饱和土壤和循环测试能力。然后，土壤特性将可用于开发先进的数值模型，以研究静态和地震荷载条件下的这些岩土工程应用。
