摘　　要：研究区位于雷州半岛东南徐闻县前山镇,距离海岸线约4 km。该区域玄武岩残积土由上至下划分为3层:(1)层红黏土、(2)层粉质黏土和(3)层全风化玄武岩残积土。文章以该区域某风电场的地勘资料为依托,通过对该区域残积土的土工试验成果、现场原位测试成果和物探成果的对比分析,揭露研究区残积土的工程地质特性,为同类地层的工程提供参考。The study zone is seated in Qianshan Township,Xuwen County,which is in southeast Leizhou Island and 4 km away from the coastal line.The basalt residual soil in the zone is classified in three layers from top to bottom:Layer①red clay,Layer②silty clay and Layer③fully weathered basalt residual soil.Based on the geotechnical data from one wind power plant developed in the study zone,the engineering geological features of the residual soil in the zone are revealed in the paper through comparison and analysis on the geotechnical test results,in-situ test results and physical exploration achievements of the residual soil in the zone so as to provide projects is with similar stratum with reference.
