摘要
以湿陷性黄土地区某风电场的风机基础为实例,介绍了试桩设计、布置以及桩基静载浸水试验过程。通过单桩静载荷浸水试验验证单桩承载力,同时该试验首次对浸水过程进行观测,试验结果为湿陷性黄土地区桩基设计中负摩阻长度的取值提供参考依据。
Based on the wind turbine foundation of a wind farm in the collapsible loess area,the paper presents the lay-out and design of test pile,and the process of static load ponding test of pile foundation.The bearing capacity of single pile was justified by static load ponding test,meanwhile observation of the ponding process was made for the first time through the test.The test results provide reference basis for determination of the value of the negative frictional resistance length during design of pile foundation in collapsible loess area.
