风电基础岩土体动参数选取分析

On the Selection of Rock and Soil Dynamic Parameters of Wind Turbine Foundation

风电基础岩土体动态参数的取值对基础设计、工程费用及工程安全影响较大,以越南某风电场的基础选型阶段对泊松比的选择为依据,结合国内相关规范及国外风电基础的技术导则,基于土动力学试验研究,提出了合理的岩土体动态参数取值的建议,可供类似工程地质条件场地参考。

Selection of the rock and soil dynamic parameters of wind turbine foundation has a great effect on the design,engineering cost and safety of the foundation.Based on the relevant domestic codes and foreign technical guidelines for wind turbine foundation,the selection of the rock and soil dynamic parameters of the foundation of a wind farm in Vietnam is introduced.Based on the experimental study of soil dynamics,suggestions are made for the reasonable selection of the rock and soil dynamic parameters.It provides a useful reference for wind farms with similar geological conditions.
