Modelling vertical geosynthetic reinforcement of soil slopes

摘要

Although the technique of vertical geosynthetic reinforcement has been used in a number of slope stabilisation schemes in the UK, it is not well understood. This paper reports the development of an experimental facility designed to quantify thebenefits attainable by such a method of reinforcement. Model slopes have been brought to failure at constant accelerations by raising the position of the ground water table aboard the Manchester University centrifuge. The experimental procedure andresults from a typical test are presented and the benefits to stability are discussed.
