Study on calculating method of horizontally reinforcement beneath embankment constructed in Karst terrain

It is often necessary to implement geosynthetics to reduce risk of sinkhole for road engineering in Karst terrain,while the theory for design and analysis is far behind the engineering practice,so it is of great important to study it.Firstly,the load on the reinforcement was analyzed,and the Terzaghi’s arch theory in ideal soil was introduced to calculate load above cavity.The reinforcement was considered composing of three portions which are free-surface portion,changeover portion and anchored ...
