Application of Safety Monitoring in Cemented Sand & Gravel Cofferdam (CSG)
安全监测在胶凝砂砾石围堰（CSG）的应用

摘要

本文主要针对面板坝和碾压混凝土重力坝基础上发展起来的一项新型筑坝技术，简称CSG（Cemented Sand ＆ Gravel 胶凝砂砾石）筑坝技术。作者介绍了在对CSG围堰监测过程中，利用监测仪器数据，剖析了CSG围堰堰体内部的变化，从而论证了围堰设计的合理性及运行期的安全性。

Abstract

This article mainly focuses on a new type of dam construction technology developed on the basis of face-face dam and roller compacted concrete gravity dam, referred to as CSG (Cemented Sand & Gravel) dam construction technology. The author introduced the use of testing instrument data to analyze the internal changes of the CSG cofferdam in the process of monitoring the CSG cofferdam, thus demonstrating the rationality of the cofferdam design and the safety of operation.
