摘要
由于风化岩场地具有风化不均匀之特点,《岩土工程勘察规范》(GB 50021—2001)对这类场地的岩土工程勘察的布孔间距具有严格规定,使得这类场地的勘察工作量往往很大。分析了高密度电阻率法在这类场地中使用的可行性和必要性,结合阿尔及利亚某炼油厂岩土工程勘察的实例,剖析了高密度电阻率法对大面积风化岩地基勘察方案设计的优化。
Generally, due to the characteristic with nonuniformity of the weathering action in weathered rock site, Chinese standard ＂Code for investigation of geotechnical engineering （GB 50021-2001 ）＂stipulates sternly the space of the exploratory hole in this kind of sites, bringing on large numbers of the exploratory holes. In this study , analyzing the feasibility and the necessity of multi-electrode electric method while carrying out geotechnical investigation in this kind of sites and using the example of the geotechnical investigation for a refinery site in Algeria, the optimization of multi-electrode resistivity method on the geotechnical investigation scheme for the large-scale weathering rock mass site is explained.
