英文摘要:
      When designing a CFRD, the deformation of rockfill is the most important factor. The determinat ion of rockf ill compaction and section zoning is the key measure for deformation control of CFRD. For rockfill compaction, when the compaction density of rockf ill increases, the deformat ion and stress of rockfill and concrete face slabs will be improved signif icantly. By means of well arrangement in rockfill zoning, the deformation of downstream rockfill would bring about certain impacts on the stress of face slabs, and the higher is the dam, the more is the impact. Rockfill zones with big difference of deformation properties would lead to occurrence of structure cracks in face slabs. Based on summarizing the related studies and numerical simulations, it can be concluded that the enhancement of standard of rockfill compact ion and improvement of sect ion zoning can greatly improve the stress and deformation properties of CFRD and thus to increase the overall safety level of the dam.
