Common Triaxial Test Study on Asphalt Concrete in the Core-wall of Hydropower Station
Hydraulic asphalt concrete, for its strong anti-seepage performance, ability to adapt to deformation and crack self-recovery ability, has more and more widespread application prospect in the water and electricity project. This experiment basis studies the qu-xue hydroelectric power station the project condition and raw material situation, the union recommendation asphalt concrete mixture ratio, uses the static three axle solidifying draining water cutting experiment, has conducted the experimental study to asphalt concrete's project performance, obtains some basic conclusions to its stress-strain relations.
Abstract A numerical scheme, based upon the Kobayashi-Tranter method with certain modifications, is given for axisymmetric punch and crack problems in elasticity. The problems are reduced to solving a system of linear algebraic equations instead of a Fredholm integral equation of the second kind. A standard program thus allows the treatment of a range of different cases. The indentation of a rigid punch on an elastic layer overlying an elastic foundation is formulated in this fashion and numerical results for various cases are presented.
