Cohesionless Soil and Small Discontinuous Reinforcing Elements in Composite Engineering Material

本研究的目的是进一步确定 在无粘性土中掺入少量， 不连续的增强元素的土壤基质。 的 第一阶段研究的结果是， 通过添加这种材料， 元素通过随机混合以及放置在 离散层。 研究将包括使用 潜在商业应用中的制造元件 包括挡土墙的设计和施工，路面系统 设计和施工，埋地管道/导管设计和 建筑和边际土地改良/车辆 增强交通能力。

The objective of this study is to further ascertain the feasibility of reinforcing cohesionless soil by adding small, discontinuous reinforcing elements to the soil matrix. The findings from Phase I study were that cohesionless soils can be appreciably strengthened and stiffened by the addition of such elements by both random mixing as well as by placement in discrete layers. The research will include the use of manufactured elements in potential commercial applications including retaining wall design and construction, pavement system design and construction, buried pipe/conduit design and construction, and marginal land improvement/vehicular trafficability enhancement.
