高密度电阻率法在风化岩地基勘察中的应用
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。
Abstract: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.
