Abstract
The quality control and schedule control are the significant technical problems in high core rock-fill dam and high concrete dam construction. The conventional quality control methods exhibit difficulty to ensure construction quality of high core rock-fill dam and to control timely schedule of high concrete dam under high-intensity continuous construction. Real-time compaction quality monitoring technology of high core rock-fill dam, real-time entire-process monitoring technology of dam materials transportation and real-time acquisition technology for dynamic information of construction quality using personal digital assistant devices (PDAs) are proposed, which realize the precise automatic online entire-process monitoring of compaction and transportation. In addition, based on an established mathematical model of concrete dam schedule real-time control, the method of timely warning and dynamic adjustment of construction schedule is proposed to provide means for schedule prediction, appropriate warning, dynamic adjustment and optimization of high concrete dam construction schedule. Furthermore, system integration technique for digital dam on Internet is presented, and a digital dam system is developed, which provides a supporting platform for dam final acceptance, safety assessment and operation management. The above-mentioned technologies have been applied to more than 10 major hydro-electric projects with achieving remarkable economic and social benefits.
