中欧岩土工程勘察分级及岩土分类对比

国外市场开拓过程中,经常遇到要求采用欧洲标准进行勘察设计,迫使参与项目建设的总承包商、勘察设计以及施工单位必须熟悉并掌握运用欧洲标准。通过对欧洲岩土标准Eurocode 7与我国岩土规范的对比,总结归纳了二者在岩土工程勘察分级和岩土分类2个方面的差异性,欧洲标准通用性和理论性较强,具有较大的灵活性,通过差异研究可为我国相关勘察设计人员进行国外项目设计提供有益的借鉴。

Comparison of the Grading of Geotechnical Investigation and the Classification of Rock and Soil between Europe and China

When exploring overseas markets, it is often required to adopt European Standards in the investigation and designing. The project participants including general contractor, surveyors and designers, and constructors have to command the use of European Standards. In this paper, we compared the Eurocode 7 and Chinese geotechnical code, and summarized their differences in the following two aspects the grading of geotechnical investigation, and the classification of rock and soil. We concluded that the Eurocode is more universal and theoretical, and is greatly flexible. The results could be used as reference for Chinese surveyors and designers in their overseas projects.
