Analysis of anomalies measured by the osmometer in a roller compacted concrete arch dam

Abstract

The water permeability of the RCC dam layer and joint surface is high, which often becomes the main channel of dam body seepage, and its safety monitoring is important. Based on the monitoring data of the osmometer of a roller compacted concrete (RCC) arch dam, this paper analyzes the abnormal seepage pressure of the dam body, and introduces the relevant inspection and treatment scheme, which can provide a reference for the construction and operation of other RCC dams.
