胶凝砂砾石坝施工质量监控系统开发及应用

胶结颗粒料坝是本文第一作者于2009年提出的一种环境友好的新坝型,分为胶凝砂砾石坝、胶结堆石坝(包括堆石混凝土坝)和胶结土坝,其强调"宜材适构"和"宜构适材"的筑坝理念,具有安全经济、环境友好、漫顶不溃等优点。与碾压式土石坝、混凝土坝等相比,胶凝砂砾石坝施工有自身特点,控制要素不尽相同。本文提出了胶凝砂砾石坝的碾压质量监控系统的总体架构和功能设计,研发了基于自主组网的超宽带三维定位技术,开发了适用于胶凝砂砾石坝的碾压监控算法和软硬件平台,并用于山西守口堡工程和四川顺江堰工程施工质量监控,实践表明该系统既适合于中小工程,也可应用于大型工程。

Development and application of the CSGR dam construction quality monitoring system

Cemented Material Dam was a new dam type of environment-friendly proposed in 2009. It is divided into three types:cemented sand, gravel androck dam (CSGRD), cemented rock-fill dam (CRD, including rock-filled concrete dam), and cemented soil dam(CSD). In the concept of dam design, it is emphasized that "the dam structure is optimized in order to make better use of local materials" and that "proper materials can be selected for the different parts of the dam in order to realize better function of structures".This new type have the benefit of "safe and economical","environment friendly" and "not fail even overtopping". And there are some important differences between CSGRD and Rolling earth rock-fill dam or RCC dam because of the different control elements. The overall framework and function design of the CSGR Dam Construction Quality Monitoring System according to "Technical guideline for cemented granular material dams" were introduced in this paper."Autonomous networking technology using UWB positioning system" and "Algorithm for rolling monitoring analysis" were also developed for CSGRD. The software and hardware platform was developed and used in Shoukoubao CSGRD and Shunjiangyan CSGRD. It is indicated that this system can be used not only in large projects but also in medium-sized and small projects.
