The Monitoring Analysis on Subsidence of the Connection Earth Dam in Chaozhou Water Supply Pivot Project
This paper introduces the field monitoring results of the connection earth dam in Chaozhou water supply pivot project. In this project, magnetic lamination-settlement measuring instrument, which is installed 3 ones in four sections each, is used to measure the settlement of the Xixi earth dam. Based on the analysis of monitoring data and simplified calculation, we get some useful conclusions. The magnetic lamination-settlement measuring instrument can directly measure the absolute value of deformation without the need to correct, calculate or measure benchmark. It’s more accurate than pipe type settlement instrument. In connection earth dam, conjoined mixing pile for resisting slippery has an effect of constraint and anti-seepage on the dam, which has played a good effect of controlling the dam settlement and the settlement difference between the ship lock and the connection earth dam. Vertical displacement of earth dam is very sensitive to the influence of factors such as water level. Settlement value of earth dam during operation is about 10.6%~38.7% of total settlement and settlement value of the head bay in ship lock during the operation is about 11.4% ~ 23.8% of total settlement.
