Stress State Analysis on a Rock Anchor RC Foundation of Wind Driven Generator

摘要

The stress state of a rock anchor reinforced concrete (RC) foundation of a wind driven generator located in the new constructed wind power station in Guodian Tieling Development Zone of China is numerically analyzed in this paper by using the large general-purpose finite element analysis (FEA) software ABAQUS, to discuss the mechanical characteristics of the rock anchor RC foundation, and validate the safety of normal use of the rock anchor foundation, and compare the developed rock anchor foundation with the traditional gravity one. The results show that the new-type RC foundation has greater advantage than the traditional one and it can completely replace the traditional gravity foundation in the condition of rock soil environment in the future.
