英国勘察规范与国标的主要区别——以乌干达某工程为例

The Major Difference Between the British Standard and Chinese Standard in Geotechnical Engineering:Example Projects in Uganda

随着"一带一路"发展战略,我国海外工程建设项目逐渐增多,由此需要深入研究英国勘察规范,探索国标英标之间的差异,以更好的指导海外工程的地质勘察工作。探讨了英标和我国现行的相关规范在工程勘察、原位测试、土工室内试验等方面的主要异同点。两国规范在原位测试、土工试验原理方面基本相同,但在土的工程分类方法、液限测量仪器规格、塑性图、直剪试验土样尺寸和变形稳定标准方面存在差异。现以乌干达某工程地质勘察为例,简要说明其勘察概况和两国土工试验方法的应用,可为海外项目提供参考。

With the development strategies of"One Belt One Road",more and more oversea projects are constructed.It is therefore necessary to have a better understanding of British Standards and other testing standards in these overseas projects.Evaluation of the differences between the British Standard and Chinese Standard can better guide the geotechnical investigation in abroad.In this paper,efforts were made to investigate the similarities and differences in existed in both standards in areas of geotechnical engineering investigation,soil laboratory as well as in-situ tests.The?rationale is?almost identical,but there are differences in soil classification,plastic?index?chart,equipment?specification of limit and shear test.The paper describes the outlines of geotechnical investigation procedures by using example?projects?in Uganda.
