Abstract
The useable soil sources for the most bidding sections of Middle Route Project of South to North Water Diversion are insufficient and using cement-mixed modified soil to replace the canal soil is a main measure for guaranteeing the canal slope stability. In the backfilling construction, large amount of surplus modified soil was produced after slope cutting and the indoor and field tests discovered that the surplus modified soil could be used as backfilling soil. In the test, the selection method of the maxi-mum dry density, construction technology and application scope of the modified soil were determined. The soil re-utilization has increased backfilling soil sources in weak expansive soil area, which could save farmland, resources and protect environment.关键词
