APPLICABILITY OF CEMENT-STABILIZED POND-MUD SOIL AS EMBANKMENT MATERIAL FOR IRRIGATION POND DAM REPAIRMENT

Abstract

Mud soil sedimented in a irrigation pond generally is high water content and very soft clayey soil. Recently, it is necessary to develop the method for utilization of such a soil, as there is little space to abandon it as industrial waste. In this paper, to confirm the applicability of the mud soil as the embankment material to repair the irrigation pond dam, a series of unconfined compression and triaxial compression tests and so on was performed to investigate the strength characteristics and stress—strain relation of cement-stabilized pond mud soil. Test results shows the follows. The stabilized-mud soil is applicable to the embankment material if the mud soil was embanked by crushing and compacting after initially stabilized with cement-stabilizer. However, it is important to controlled the initial stabilizing time, the crushed size and strength of initial stabilized-mud soil under construction, because the strength behavior of the crushed and compacted cement-stabilized mud soil is greatly affected by these three factors.
