rock fill

Settlement of earth-rockfill dam is mainly influenced by aging deformation and regression model is usually adopted for settlement analysis.

The new dam consists of an earth core rockfill embankment and a concrete transition at the left abutment.

Particle breakage of rockfill materials is serious under high pressure, and its influence on deformation of rockfill cannot be ignored.

While for bedding rockfill which has moderate or even low permeability vacuum saturation can be used to save much time.

It is recommended that the degree of compaction be used to determine the construction compaction criteria of rockfill materials in field.

Asphalt concrete core-wall rockfill dam is one of the main types of earth-rock dam.

The construction of upstream slope of cushion materials of faced rockfill dam is one of key construction items.

The compact rockfill materials are of the properties of high permeability, low compression, low failure strain and high shear strength.

The breakage volumetric strain of rockfill is positive and increases with the increase of axial strain in a trend of hyperbolic curve.

The grain crushing of rockfill materials with high stress level has significant influence on its strength and deformation mechanisms.

The modified model can preferably reflect the influence of particle breakage on the mechanical behaviour of the rockfill materials.

The testing results show that the maximum dry density of rockfill should be tested by the platform vibrator.

The deformation monitoring system mainly covers the rockfill body of the dam, concrete face and peripheral joints.

Therefore it is necessary to take reinforcement measures on the upper part of high earth-rockfill dams in earthquake region.

On the infinite deep pervious foundation, the earth - rockfill dams often take the hanging vertical cut -off wall to control the seepage.

The stress-strain behaviour of rockfill is seriously influenced by the particle breakage.

The Mohr failure envelopes for rockfill exhibit significant nonlinearity at high stresses.

The design method and features of coyote blasting in quarrying rockfill material for the Doulingzi hydro power project are described.

Seepage exists widely in earth-rockfill dams in water conservancy projects.

Based on stress control triaxial compression test and consolidation test, the indeterminacy of test result for rockfill was studied.

In this paper, the phenomenon of hydraulic fracturing caused by water injection tests in dangerous earth-rockfill dams is analyzed.

The creep of the rockfill body of the Shuibuya dam has some effect on its stress and deformation.

and the seepage coefficient decreases when the mudstone content in rockfill increases.

Dynamic statistical model of earth-rockfill dam is proposed in this paper.

By making use of the merits of artificial rockfill, a detailed statistic and sieving analysis of particle breakage was performed. 3.

Since 1970 's, ten and more Poured Asphaltic concrete core Rockfill Dams (PCRD) have been built in the northern region of China.

According to comprehensive analysis, it is thought that hydraulic fracturing in core of earth-rockfill dam is hard to occur.

The Baiyekou Reservoir's dam is a concrete facing rockfill dam.

Shuibuya Dam is currently the highest concrete face rockfill dam in the world.
