RIA: Toward More Reliable Characterization of Soil Consolidation Properties

这项研究的目标是开发更可靠， 基于试验的恒应变率试验分析 技术，特别是在快速应变速率。一台新电脑 自动CRS固结仪将用于进行 一维（1-D）固结试验的沉降粘土。 该提案有以下目标：1.开发计算机 自动CRS; 2.在各种应变率下进行CRS测试， 表征超静孔压分布; 3.比较 这些结果与其他一维固结试验的结果相同; 4. 评估CRS检测快速测定的适用性 水力传导率; 5.将结果纳入统一的 时间相关内聚行为的数据库。

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.
