水利工程土石坝坝体施工填筑质量变形监测方法研究

Research on Monitoring Method for Quality Deformation of Earth-rock Dam Body Construction and Filling in Water Conservancy Projects

由于传统变形监测方法的监测间隔时间不稳定,导致土石坝位水平和垂直位移的变形监测值和实际结果不符,为此提出水利工程土石坝坝体施工填筑质量变形监测方法。设置土石坝变形监测点,确定监测时间间隔,设计合理监测周期,监测土石坝垂直位移和水平位移,完成水利工程土石坝坝体施工填筑质量变形监测方法。实验结果表明:新方法得到的水平和垂直位移监测值和实际结果能够保持一致,满足土石坝施工填筑规范要求,能够防止事故的发生。

Due to the unstable monitoring interval of traditional deformation monitoring methods,the deformation monitoring values of the horizontal and vertical displacements of earth-rock dams are inconsistent with the actual results.Therefore,a deformation monitoring method for the construction and filling quality of earth-rock dams is proposed.This research set up the deformation monitoring points of earth-rock dams,determined the monitoring time interval,designed a reasonable monitoring period,monitored the vertical and horizontal displacements of earth-rock dams.The experimental results show that the horizontal and vertical displacement monitoring values obtained by the new method can be consistent with the actual results,meet the requirements of the earth-rock dam construction and filling specifications,and can prevent accidents.
