| Researches on the induced trench method using compressible materials such as clay, mud, straw have been performed to reduce the load acting on buried conduits under a high fill in USA and Canada. And in-situ tests on load reductionmethod using EPS block as a compressible inclusion have been performed in Japan and Norway. Using a EPS block as a compressible materials can have various benefits such as cost-effective design, enlargement of safety and easy construction of structure under high fills. This paper analyzes the arching material function of EPS which can result in reduction of earth pressure by arching effect in Corrugated Steel Pipe. A series of tests were conducted to evaluate the reduction of earth pressure on conduits using EPS. Based on field test it is found that the magnitude of vertical earth pressure on conduits was reduced to about 35¡40% compared with conventional flexible conduit systems. |
