The goal of the project is to test a new rheological slope stability model. This rate-of-deformation dependent and visco- plastic model will be tested with data from a specific landslide which has been collected for years now. The project is divided into four phases: the first, field sampling; the second, laboratory testing, e.g., soil identification, triaxial and simple shear strength, and creep tests; the third, analysis of the data with deformation being calculated using the rheological model; and the fourth, preparation of report and papers. The results of the project will provide a measure of the appropriateness and effectiveness of limiting-equilibrium slope stability models currently used in comparison with this new technique for geotechnical design and evaluation of slopes.

该项目的目的是测试一种新的流变边坡稳定模型。这个依赖于变形速率和粘塑性的模型将用多年来收集的一个特定滑坡的数据进行测试。该项目分为四个阶段：第一阶段，现场取样；二是实验室试验，如土体识别、三轴和单抗剪强度、蠕变试验；第三，利用流变模型对计算变形的数据进行分析；第四，准备报告和论文。该项目的结果将提供一种衡量目前使用的极限平衡边坡稳定模型的适当性和有效性的方法，并将其与这种用于边坡岩土设计和评价的新技术进行比较。
