西埠上坝劈裂灌浆

西埠上坝劈裂灌浆 English Version

摘要: 本文通过西埠土坝坝体劈裂灌浆试验,系统地观测了孔隙水压力、土压力、灌浆压力、裂缝开展、坝体变形、泥浆和坝体固结等的变化过程;初步论述了劈裂灌浆的规律,给出了控制劈裂灌浆的压力和浆液收缩等计算公式。对改进灌浆工艺,提高灌浆效果也提出了建议。

Abstract: By the observation of the in-situ fracturing-grouting tests of Xibu Dam, the variational processes of the pore water, earth and grouting pressures, cracking, deformation of the dam, consolidations of the dam and slurry etc. are presented in this paper. The regularities on the fracturing-grouting are preliminarily described. The formulae for controlling the fracturing-grouting pressure and contraction of the slurry are given, and the reasonable proposals are also presented so as to improve the technology and increase the effect of the grouting.
