Study of Effect of Distinction Between Primary and Secondary Rockfill Zones of Rockfill Dam
摘要
Abstract
The justifiable distinction between primary and secondary rockfill zones directly effects the stress,deformation, staility and engineering cost of the concrete face plate. This paper researches on the three different rockfill zones schemes such as supine slope 1 : 0.2, prone slope 1 : 0.2, and prone slope 1 : 0.6 based on the Liaoye concrete-faced rockfill dam with the Duncan-Chang model and the software ANSYS. The results show that the primary and secondary rockfill zones scheme with prone slope 1 : 0.6 is best, comprehensively considering stability, deformation and stress level; this conclusion can provide reference for similar rockfill dam design.关键词
