摘　　要：本文通过对拟建风电场项目的3根桩长10m,桩身直径为800mm的机械钻孔混凝土灌注桩试验桩进行单桩水平静载试验,准确测定出该工程的试验桩7#、8#、9#三根单桩水平承载力特征值不小于60KN,7#单桩的桩顶水平最大位移量为3.73mm、8#单桩的桩顶水平最大位移量为2.38mm、9#单桩的桩顶水平最大位移量为1.36mm。为项目下一步的设计提供了依据。This paper conducts a single-pile horizontal static load test on three mechanically drilled concrete castin-place pile test piles with a length of 10 meters and a pile diameter of 800 mm in the proposed wind farm project,and accurately determines the test piles of the project The characteristic value of the horizontal bearing capacity of the three single piles of 7#,8#and 9#is not less than 60KN,the maximum horizontal displacement of the top of the 7#single pile is 3.73 mm,and the maximum horizontal displacement of the top of the 8#single pile is 2.38 mm.The maximum horizontal displacement of the top of the 9#single pile is 1.36 mm.It provides a basis for the next design of the project.
