RIA: Toward More Reliable Characterization of Soil Consolidation Properties

本研究的目标是开发更可靠的，基于实验的恒定应变速率（CRS）测试分析技术，特别是在快速应变速率下。一种新的计算机自动CRS固结装置将被用于对再沉积粘土进行一维（1-D）固结试验。该建议有以下目标：开发计算机自动化CRS；2. 在不同应变速率下进行CRS试验，表征超孔隙压力分布；3. 将这些结果与其他一维巩固试验的结果进行比较；4. 评估CRS试验在快速测定水导率方面的适用性；5. 将结果合并到时间相关内聚行为的统一数据库中。

The goal of this research is to develop more reliable, experimentally-based constant-rate-of-strain (CRS) test analysis techniques, particularly at fast strain rates. A new computer automated CRS consolidation apparatus will be used to conduct one-dimensional (1-D) consolidation tests on a resedimented clay. The proposal has the following objectives: 1. develop computer automated CRS; 2. conduct CRS tests at various strain rates and characterize the excess pore pressure distribution; 3. compare these results to those from other 1-D consolidation tests; 4. assess the CRS test's suitability for rapidly determining hydraulic conductivity; 5. incorporate the results into a unified data base of time-dependent cohesive behavior.
