TEST EMBANKMENT DAM OF FRACTURE GROUTING

Fracture grouting is widely used to seal leaks through the poorly compacted cohesive fill embankment dams in China, and review of boreholes in an embankment has offered some direct evidence of the mechanism. The paper presents results of a field test which provide verification, and suggest ways to improve the technique of fracture grouting. It was found that fracturing pressure was directly related to the stress of the dam at which fracturing started. The grout veins were parallel to the dam axis and vertical. The mode of expansion of grout vein and the thickness of the vein could be controlled to a certain extent by choosing appropriate grouting details.
