This paper makes a systematic research on the properties of dam materials for HCRFD (High Core Rock Fill Dam), and initiates with a modification method of static & dynamic constitutive model; a study on the compaction property of materials mixed with gravel soil, compaction standard and the detecting methods for filling quality; the papers has also explored into the new technology to realize a comprehensive, real-time, online and automatic monitoring on the various parameters of filling construction and compaction via transmission network by adopting technologies of PDA、GPS、GPRS.
