葛洲坝水利枢纽大江上游围堰混凝土防渗墙的位移观测及分析

Observation and Analysis of Displacement of Concrete Watertight Core on the Upstream Cofferdam of the Main Channel of Gezhouba Project

本文阐述了葛洲坝枢纽大江上游围堰混凝土防渗墙内部水平位移观测的成果。文中应用数理统计方法,综合围堰的施工过程、观测过程和结构受力机理,对观测资料进行了全面分析,提高了成果的可靠性。

This paper describes the observation results of internal horizontal displacement of concrete watertight core on the upstream cofferdam of the main channel of Gezhouba Project.By use of the applied mathematic statistics, this paper analyses the observational data and considers the construction process of the cofferdam,mechanism of structural load and measuring methed. As a result,the reliability of the observation results is increased.
