摘　　要：采用静力触探技术在渤海某海上平台场址工程进行了原位测试。结合静力触探获取的海底土锥尖阻力、侧摩阻力和孔隙水压力等方面的连续原位测试数据及以往学者提出的土类判别法对该场址工程中土层进行了划分。结果表明锥尖阻力和孔隙水压力受锥尖周围土性的影响明显,当地层发生变化时锥尖阻力和孔隙水压力会发生较大变化。对比分析,Eslami和Fellenius(1997)土类判别法能较准确判别该场址工程中土质类型。The in-situ testing was conducted by CPT in an offshore patform project of Bohai Sea. Combining the continuous in-situ test data,such as the seabed soil tip resistance,side friction and pore water pressure obtained from the CPT and the method of soil type discrimination put forward by the former scholars,the soil was divided. The results show that the tip resistance and pore water pressure were significantly affected by the cone surrounding soils. Therefore,the tip resistance and pore water pressure changed greatly when the local layer changes. Through comparing and analyzing,the method proposed by Eslami and Fellenius( 1997) can accurately determine the type of soil in the project site.
