Application of Non-Adhesive Pre-Stressed Anchor Cables in the Treatment of the Crack of Dam

Abstract:

Mass concrete ,such as dam concrete will appear vertical and horizon cracks due to various reasons. and these cracks will threat the safe operation and limit the economic benefits of the dam. pre-stressed anchor cables have been widely used as a main reinforcement method. the paper focuses on the cable construction technique and describes its effective reinforcement capabilities combined with the reinforcement of Panjiakou dam.The horizontal crack of Panjiakou concrete gravity dam is an activity crack, which varies with season and temperature change. Results of many years of test and research showed that the application of "combining caulking with draining and pre-stressed Anchorage" in the treatment of the crack was effective.At present, reinforcement construction has been completed, and the project operates well.
