Consolidation is a process in which water is squeezed out of soils as a function of time, with a resultant reduction in soil volume. The resulting problems involve time dependent settlement of buildings, tanks, embankments, fills, and other "structures." In case of dredged materials and waste "slimes" from the mining industry, the problem is usually that there are huge quantities of waste material that we wish to concentrate to a smaller volume through the consolidation process. "Design" involves predicting the rate of consolidation so ample storage areas can be planned and used efficiently. Classical analyses involve grossly simplifying assumptions and have limited accuracy, requiring that the answers be adjusted using "engineering judgment." In this proposal, the PI proposes research to develop analytical methods that account for large strains, multidirectional water flow, and other such effects, thus allowing realistic solutions to problems involving efficient and economical disposal of such materials.

固结是一个过程，在这个过程中，水被挤出土壤， 随着时间的推移，土壤体积也随之减少。 的 由此产生的问题包括建筑物的时间依赖性沉降， 罐、填料、填充物和其他“结构”。“如果 挖掘的材料和采矿业的废物“泥”， 问题是通常有大量的废料 我们希望通过 巩固进程。 “设计”包括预测 整合，以便规划和使用充足的存储区域 有效地 传统的分析涉及严重简化 假设和有限的准确性，要求答案是 使用“工程判断”进行调整。“在这项提案中，PI 建议研究开发分析方法， 大应变、多方向水流以及其他此类效应， 从而允许现实的解决方案， 经济地处理这些材料。
