Centrifuge and Full Scale Modelling of Geotextile ReinforcedCohesive Soil Structures

本研究将使用一系列土工离心模型 探讨土工布加固建筑土的效果 回填土为粉土时边坡及挡土墙的稳定性 或者粘土。四点重点将放在对斜墙的影响上 不同倾角的稳定性;排水 系统的特性，包括渗透率的 土、土工织物的平面渗透性和垂直渗透性 土工织物加固层之间的间距;长度 加固;以及在粘性土中加入石灰。 最终的结果将是开发一个简单的分析 用于设计墙壁和斜坡的工具， 在粒状土壤不容易获得的地区建造。

This research will use a series of geotechnical centrifuge models to explore the effect on geotextile reinforced constructed soil slope and soil retaining wall stability when the backfill is silt or clay. The four point focus will be on the effects on sloped wall stability of different batter angles; of the drainage characteristics of the system which includes permeability of the soil, the in-plane permeability of the geotextile, and the vertical spacing between layers of geotextile reinforcement; of the length of reinforcement; and of the addition of lime to the cohesive soil. The ultimate outcome will be the development of a simple analytical tool for design of walls and slopes which are less expansive to construct in areas where granular soils are not readily available.
