瀑布沟水电站大坝砾石土心墙施工监测分析

Analysis on construction monitoring of gravel-soil core of rock fill dam of Pubugou Hydropower Station

瀑布沟水电站砾石心墙堆石坝,最大坝高186 m,根据施工期监测砾石土孔隙水压力、土压力及沉降变形,说明在砾石土心墙施工时,必须适度地控制含水量和填筑进度。

The Pubugou rock fill dam with gravel-soil core is 186 m high . According to the monitoring data on pore wa- ter pressure, soil pressure and settlement, it is worth notice that the moisture content of the gravel-soil and the construc- tion progress of the core wall must be well controlled.
