Abstract:The soil material for the Guanlu Reservoir surrounding dam filling is mainly from the excavated soil of the oldsurrounding dam and the reservoir basin. To improve the filling and rolling quality of the surrounding dam, an intelligentcontrol construction method for compaction degree is adopted to realize real-time and precise control of the moisturecontent and compaction degree of the filled soil. This method improves the construction eflicieney and the stability ofconstruction quality, and ensures the rolling quality of the reservoir surrounding dam.
