摘要
通渭县华家岭49.5 MW风电工程场区黄土梁覆盖层最大厚度55.4 m,风积马兰黄土最大厚度16.2 m。工程勘察中首先通过对场区覆盖层的岩性分层及成岩时代的划分并结合区域工程经验,初步判定了场区黄土的湿陷性,通过勘探取样、室内试验及对试验数据的分析和钻孔标贯试验等方法对湿陷性黄土进行了复判。
In 49.5 MW Huajialing wind farm site, Tongwei County, the maximum thickness of the loess ridge overburden is 55.4 m, the maximum Mala loess aerolian deposited is 16.2 m.In the investigation , the lithology stratum and stratification age of the overburden in the site are classified.Furthermore, the site loess collapsibility is judged and determined primarily based on the engineering experience. Through sampling, lad test, test data analysis and SPT, the collapsible loess is rechecked.
