Rockfill Modulus and Settlement of Concrete Face Rockfill Dams
Journal of Geotechnical and Geoenvironmental Engineering, 2003A method is presented for estimating the modulus of compacted rockfill in dams based on the particle size, unconfined compressive strength of the rock, compaction layer thickness, compactive effort, and the applied vertical stress. Also presented are methods for predicting the crest settlement and face slab deformation of concrete face rockfill dams ...

Rockfill Dams: Review and Statistics
Journal of the Power Division, 1958This paper reviews present practices. It develops a definition, classification and terminology for such dams and for those using earth in addition to rock fill. It discusses the advantages of deck-type dams; also settlement and economy of rock-fill dams. In its appendix it lists rock-fill dams constructed in the United States and in foreign countries.

A practical method for estimating the shear strength of rockfill is developed. The peak drained friction angle π(prime) is found to be closely related to that of rock joints. In both cases the values of π(prime) are dependent on sample size, stress level, surface roughness, and on the uniaxial compression strength of the rock.

Hydraulic Conductivity Of Rockfill
Journal of Hydraulic Research, 1978Dimensionless equations for the hydraulic conductivity of crushed rock and river gravel have been developed on the basis of approximately 1250 permeameter tests. Experimental data of a number of researches were used in the correlations. Grain sizes varied from .55 to .79 mm and pore Reynolds numbers were in the range of .001 to 20,000.

The monitoring of internal deformation in rockfill dams using preburied flexible pipelines is a promising technique; however, achieving precise measurements over a long-range pipeline is crucial and challenging.

Karl Terzaghi, a major contributor to progress in embankment dams, made significant contributions to the understanding of properties of rockfill and to the improvement of design of the concrete-face rockfill dam. His contributions are noted and followed by a history of parallel development of earth core and concrete-face rockfill dams and the impact of

The 260-m high rockfill dam of the Tehri Project in India is to be placed at a site that has complex geology. The dam foundation will be of highly jointed and sheared phyllitic rocks. The region is also seismically active. The design and construction problems examined are: (1) The location of the dam axis; (2) the dam section; (3) the approach to ...

In geotechnical engineering, time-dependent settlement is normally associated with the process of consolidation. In this, settlement behaviour is determined by the rate at which water is able to flow from the voids under a hydraulic gradient, allowing particles to slide into a more compact arrangement.
