摘要

针对湿陷性黄土地区风力发电机基础的安全施工,通过对湿陷性黄土的地震强度、地层岩性、湿陷性、地下水的评价论证,结合工程量、工程造价因素进行方案比较和优化,得出采用扩底端混凝土灌注桩的施工方案,在湿陷性黄土区风机基础施工中应用,取得了良好效果。
Aiming at the foundation construction of wind power generator in wetting and subsidinging loess area,through the evaluation and reasoning for the earthquake intensity,the lithology,wetting and subsidinging of strata and underground water,combining with the factor of size and cost of project,makes comparison and optimization of the schemes,draws the conclusion that using the construction schemes of expanding bottom priming concrete piles,which is applied in foundation construction of wind power generator in wetting and subsidinging loess area.
