汾河二库大坝基础固结灌浆试验

Consolidation Grouting Test for Dam Foundation of Fenhe Reservoir II

本文以汾河二库大坝坝基地层岩性为例,采用钻孔→洗孔→压水→灌浆→插入钢筋及封孔等固结灌浆试验工艺,通过对两个区的灌浆生产性试验,提出大坝坝基固结灌浆参数,为同类地层条件的固结灌浆提供参考依据。

Before constructing of the RCC dam of the Fenhe Reservoir II,the consolidation grouting for the dam foundation was carried out .In order to provide some main parameters for the consolidation grounting mentioned above,the consolidation grouting test including mainly the determination of the grouting pressure,grouting takes,and especially the detecting of uplift value by the grouting had been made.In this paper,the regime of the above test is introduced.
