摘要： 以中海油惠州千万吨炼油工程勘察成果为例，分析了大亚湾石油工业区岩石地基的工程特性，列出岩石地基的物理力学指标统计值，并同经验参考值进行了对比分析。同时分析了采用声波测试成果进行基岩风化带划分的必要性，并提出了可将基岩风化带定义为主层，然后按照不同岩性划分亚层的岩土工程分层原则。

Abstract: The geotechnical properties of bedrock at Dayawan area are discussed in this paper. The project site is the China National Offshore Oil Company (CNOOC)'s Ten Million Tons Refinery Facility in Huizhou City. The mechanical properties of tested samples are statistically analyzed and compared with the code suggested values. The bedrock weathered zones are evaluated by using the ultrasonic wave velocity testing. The principles of the weathered zone subclassifications are also presented in this paper.

Key words: rock foundations, engineering properties, dayawan area
