浅谈国外岩土工程勘察项目工作模式及应用

Procedures and Application of Foreign Geotechnical Engineering Investigation Projects

国外岩土工程勘察模式和国内相比有很大的不同,基于印度尼西亚某火力发电厂岩土工程勘察项目工作成果,从岩土工程勘察工作管理模式、勘察标准与依据、勘察设备、原位测试方式、勘察报告编写与解读等方面对国外岩土工程勘察项目的工作模式进行分析和总结。在国外勘察管理模式上提出了三种概念模式;在勘察设备上重点对比了国内外标准贯入设备和静力触探设备;在勘察报告方面提出了国内外两套报告编写特点及主要用途;同时基于如何做好国外岩土工程勘察项目管理以及技术储备上提出了五点建议。研究成果可为今后类似国外岩土工程勘察项目提供借鉴和参考。

Compared with the normal geotechnical practice in China,the procedures overseas might be significantly different.As a comparative example,a case history of the geotechnical investigation of a coal burning power plant in Indonesia is presented in this paper.The full geotechnical investigation procedures from the aspects management,standards as well as specifications,equipment,in-situ test methods,data interpretation and preparation of the investigation report are analyzed and summarized.Three conceptual procedures are suggested for the overseas soil investigation projects.The conventional standard penetration test equipment and static cone penetration equipment used in domestic and abroad are especially compared.From the geotechnical report perspective,the domestic and foreign procedures are also introduced.Five suggestions of how to conduct overseas geotechnical engineering investigation project in the project management and the technical procedures are proposed in the paper.The results of this paper can provide a reference for similar foreign geotechnical engineering investigation projects in the future.
