Abstract

The results of large scale static and cyclic triaxial tests for the Siah Bishe rockfill are presented. The test specimens are made of a modeled gradation with Dmax of 5 cm, reduced from the real Dmax of 80 cm by scalping method. Static triaxial tests resulted in the rockfill shear strength parameters within the expected range. The cyclic triaxial strength tests showed that the dam body rockfill failure criterion is not affected by earthquake loading. On the other hand, the cyclic triaxial parametric tests results were used to define shear modulus and damping curves of the compacted rockfill, for numerical analyses. These results are different from the shear modulus and damping curves found in the literature for coarse materials.

Static and Cyclic Triaxial Testing of a Compacted Limestone Rockfill

Chicago, Illinois

The results of large scale static and cyclic triaxial tests for the Siah Bishe rockfill are presented. The test specimens are made of a modeled gradation with Dmax of 5 cm, reduced from the real Dmax of 80 cm by scalping method. Static triaxial tests resulted in the rockfill shear strength parameters within the expected range. The cyclic triaxial strength tests showed that the dam body rockfill failure criterion is not affected by earthquake loading. On the other hand, the cyclic triaxial parametric tests results were used to define shear modulus and damping curves of the compacted rockfill, for numerical analyses. These results are different from the shear modulus and damping curves found in the literature for coarse materials.
