| 中文摘要:大唐国际东营风电一期工程拟建风电场场区位于东营市东部沿海区域，拟建场地上覆第四系地层,结构松散，厚度较大,工程性质较差，地基强度较低，不能满足重要建（构）筑物对其强度及变形的要求，且场地内的饱和粉土及砂土在地震影响烈度达Ⅶ度时将可能产生液化现象，因此需进行地基处理。根据现场岩土条件,拟采用预应力高强混凝土管桩（PHC），需进行桩基原体试验。主要介绍了桩基原体试验施工过程、检测方法及试验成果等。 |

| Abstract:Dongying wind power first phase project of Datang International was planed in the position of the coastal area east of Dongying City, the overlying quaternary strata is thick and loose with poor engineering property and low-intensity ground, can not satisfy the requirement of strength and deformation for the important building (structure), the saturated silt and sand clay may produce liquefied natural phenomenon in the Ⅶ degrees of earthquake intensity. According to the site geotechnical conditions, the foundation treatment was planed with pre-stressed high-strength concrete pipe pile (PHC), and the prototype testing was needed. The paper introduced the construction course of prototype testing for pile foundation, detection method and test results. |
