Cohesionless Soil and Small Discontinuous Reinforcing Elements in Composite Engineering Material

本研究的目的是通过在土壤基质中添加少量不连续的加筋元素来进一步确定加固无粘性土的可行性。第一阶段研究的结果是，通过随机混合以及在离散的层中放置这些元素，无粘性土壤可以明显地得到加固和硬化。研究将包括在潜在的商业应用中使用制造的元素，包括挡土墙的设计和建造、路面系统的设计和建造、地下管道/管道的设计和建造，以及边际土地改善/车辆通行能力的提高。

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.
