Abstract

The technologies for construction of roller-compacted concrete (RCC) dams have been considerably developed during recent years in China. At the time being, they have been successfully applied to the constructions of even extreme-high gravity dams and medium to high arch dams. There are a few of hundreds of RCC dams (RCCD) under design and/or construction in China. One of the main concerned technical problems according to the construction is about the understanding of the property of seepage in RCCDs and the relevant theory and methods for the control of the seepage. In order to overcome the problem, the senior author has been engaged in a wide study on the property and methods for control of seepage in RCCDs for more than 10 years. The property of seepage, measures for watertightness and drainage, optimal design and construction schemes for control of seepage in the dams have been essentially understood either in theory and practice. The results have been applied for the construction and the backanalysis of several dams. The paper describes the research findings in detail with respect to the theoretical fundament and their application for a high RCC gravity dam.

Secondary title:	Metode za kontrolo pronicanja vode skozi pregrade iz valjanega betona z meritvami vodotesnosti in drenaž
Secondary abstract:	Kitajska je v zadnjih nekaj letih močno razvila svojo tehnologijo izgradnje jezov iz valjanega betona (beton RCC). Trenutno se ta tehnologija uspešno uporablja pri izgradnji izredno visokih gravitacijskih jezov, pa tudi pri izgradnji srednje visokih in visokih ločnih jezov. Na Kitajskem trenutno projektirajo ali gradijo kakšnih sto jezov iz valjanega betona. Eden glavnih tehničnih problemov pri takšni gradnji je razumevanje pronicanja vode skozi valjani beton ter potreba po razvoju ustrezne teorije in metod za nadzor pronicanja. Prvi avtor tega članka zato že več kot deset let sodeluje v obsežni študiji o lastnostih valjanega betona in metodah za nadzor pronicanja. Študija podaja teoretične osnove ter rezultate terenskih raziskav o pronicanju vode, ukrepih za doseganje vodotesnosti, drenaži, optimalnem načrtovanju in nadzoru pronicanja. Rezultate te študije smo koristno uporabili pri izgradnji in pri povratnih analizah številnih jezov. Članek podrobno opisuje raziskovalne dosežke študije, teoretske osnove ter njihovo praktično uporabo pri visokih gravitacijskih jezovih iz valjanega betona.
