SMALL MODEL EXPERIMENT FOR EFFECT OF GROUND REINFORCED WITH LOGS UNDER LOW CONFINING STRESS

Abstract

 Small model test is conducted to verify the shear effect of composite ground reinforced with logs. In this test, following contents are verified. the improvement effect of ground with or without logs, the interval of logs and the effect of confining pressure are verified. As the result, As the number of log increases and driven interval narrows, the displacement is not large with surcharge. It is clarified from the photo at the experiment that the displacement is small as driven interval narrows. The final load increases due to the reinforce of the log. It is considered that the ground strength is strong under shear deformation due to the reinforce of the log.
