摘　　要：目前,海外工程项目的岩土工程勘察多采用欧美标准,深入学习并消化欧美标准有助于中国企业执行海外项目。针对国内外岩土工程勘察中常用的扁铲侧胀试验和圆锥动力触探试验,从设备规格、适用范围、试验技术要求和试验成果应用4个方面,重点分析对比了美国ASTM标准和中国岩土工程标准体系的差异。结果表明:中美标准中扁铲侧胀试验设备规格基本相同,局部设备、技术要求、公式、操作和数据记录存在少许差异;中美圆锥动力触探试验技术要求没有太大差异,但在试验终止条件和试验数据记录要求等方面有一定区别。研究结果可为中国实施“走出去”战略的勘察设计企业提供参考。Currently,most of the geotechnical investigation of overseas engineering projects adopt European and American standards,it is necessary for Chinese survey and design enterprises to conduct in-depth study and digestion of European and American standards for implementing overseas projects.Aiming at the Flat Plate Dilatometer Test and Dynamic Cone Penetration Test commonly used in geotechnical engineering investigations at home and abroad,the differences between American ASTM standards and Chinese geotechnical engineering specifications and standards were analyzed and compared from four aspects:equipment specifications,scope of application,test technical requirements,and application of test results.The results showed that the specifications of Flat Plate Dilatometer Test equipment in Chinese and American standards were basically the same,with slight difference in local equipment,technical requirements,formulas,operations and data records.There was no significant difference in the technical requirements of Dynamic Cone Penetration Test between China and the United States,but there were some differences in test termination conditions and test data recording requirements.The research results can provide reference for survey and design enterprises in China to implement the go global strategy.
