RIA: Foundation Soil Response of Embankments During Stage Construction

本研究的目的是探讨压力- 相对弱粘聚力应变-强度特性 地基土分阶段施工。 各向异性固结直剪试验将 在应力条件下对土壤样品进行 在舞台建设中发挥作用的代表。 反映可塑性和矿物学的不同土壤类型， 超固结比和固结应力比 追究利用实验结果和现场 验证后，将提出改进的最终建议 分阶段建造的建筑物的设计。

The objective of this research is to investigate the stress- strain-strength behavior of relatively weak cohesive foundation soils during stage construction of embankments. Anisotropically consolidated direct simple shear tests will be performed on soil samples under stress conditions representative of those acting during stage construction. Different soil types reflecting plasticity and mineralogy, overconsolidation ratio and consolidation stress ratio will be investigated. Using experimental results and field verification, final recommendations will be made for improved design of staged constructed embankments.
