摘　　要：内蒙古某风电场拟建区域属于山地及丘陵地貌,场址地势陡峭,传统勘探设备难以布置,因此采用坑探与电测深法相结合对整个风电场进行岩土工程勘察。首先采用DDC-6型电子自动补偿仪对该风电场拟选的33台风机塔位视电阻率进行测定,再通过电法数据处理系统Geo Electro软件对电测深数据进行反演解释,最后与探井资料进行对比分析,确定整个场地内各风化层与视电阻率的对应关系,从而推断各风机塔位的风化层厚度。通过实践验证电测深法反演结果基本符合该风电场地层实际情况。The proposed area of some wind farm region of mountainous, hilly terrain and steep terrain in Inner Mongolia located in the sites. The traditional exploration equipment is difficuh to arrange, so use electrical sounding with test pit to make geotechnical engineering investigation for the entire wind farm. Firstly, measure the apparent resistivity of 33 turbines to be selected to Towers with DDC-6 electronic instrument automatically compensates, and then the data processing system by electrical GeoElectro software for electrical sounding data inversion interpretation, and the final exploration well data were analyzed to determine the correspondence between the various venues across the regolith and apparent resistivity, to infer the regolith thickness of each wind turbine tower position.
