A complete scheme for solving the key scientific problems associated with high-standard, high-intensity continuous construction of high arch dams was presented. First, based on a coupling analysis of construction system decomposition and coordination for a high arc dam, a mathematical model for real-time control of construction quality and progress that considers complex constraints was developed. Second, a method of progress control was proposed based on a dynamic simulation. Third, a dynamic quality control mechanism was established based on construction information collected using a PDA. Fourth, a system for integrating collected information, progress simulation and quality control analyses under a network environment was developed. Finally, these methods were applied to a practical project to show that each aspect of a construction process can be managed effectively and that real-time monitoring and feedback control can be realized. Our methods provide new theoretical principles and technical measures for quality and progress control in the high arc dam construction process. construction quality, construction progress, dynamic simulation, real-time control, network, high arc dam Citation: Zhong D H, Ren B Y, Li M C, et al. Theory on real-time control of construction quality and progress and its application to high arc dam.High arc dams are generally located in mountainous regions or in gorges. These areas have complicated geology, steep terrain, deep valleys, high stresses and limited space. The length of the construction period and the safety of whole project are directly affected by construction progress and quality of high arc dam [1]. The construction process is complicated and dynamic. It can only be semi-structured and involves randomness, uncertainty. This uncertainty is influenced by many factors including the natural environment, structural form of the dam, technology, organization modes, machinery and building materials. This complex construction process cannot be represented by a simple mathematical model. Real-time control technology is an effective method for studying the technical problems associated with high-standard, high-intensity continuous high arc dam construction. Construction quality and progress control are important issues both domestically and internationally. By combining Auto CAD, P3 and ArcViewGIS, Poku et al. [2] developed the PMS-GIS system, which shows the progress of housing construction in a dynamic 3D image. Leung et al. [3] developed a construction site video monitoring system that integrates a wireless network, network cameras and a web-based collaborative platform for controlling building construction quality and progress. Xiao et al.[4] effectively controlled bridge construction quality using fast internet-based data acquisition and transmission as well as control decisions. Zhu [5,6] proposed numerical monitoring of concrete dams. Utilizing finite element simulations of dams during each phase in the construction process, the temperature field and stress field at the t...
