糯扎渡高心墙堆石坝坝料特性研究及填筑质量检测方法和实时监控关键技术

Study on the properties of dam materials of HCRFD,filling quality detecting methods & critical real-time monitoring techniques

系统研究了糯扎渡水电站高心墙堆石坝坝料特性,提出了静动力本构模型修正方法和水力劈裂发生的物理机制;研究了掺砾土料的压实特性、压实标准及填筑质量的检测方法;采用PDA、GPS、GPRS技术,通过传输网络,实现大坝填筑碾压各项参数的全面、实时、在线、自动监控的新技术。

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.
