摘要： 沙特拉比格 2×660 MW燃油电站地基为特殊的珊瑚礁灰岩。运用现场钻探、平板载荷试验、波速测试等勘探手段和方法，进行了重度、抗压强度等室内岩土特性试验，分析了沙特红海珊瑚礁灰岩的物理力学性质。该工程成果的应用为珊瑚礁岩土特性研究及地基基础方案的选择提供了宝贵的工程经验。同时，作为涉外项目，从勘察方案制定、技术协调、现场实施等环节的运作也积累了经验，提升了涉外项目勘察设计水平，对开拓海外市场具有积极意义。

Abstract: The subsurface soils underneath a proposed 2X660MW power plant consist of limestone of coral reef origin. In order to characterize the engineering properties of limestone of Red Sea coral reef origin, the geotechnical investigation program included field conventional test boring, plate loading test and acoustic velocity testing and laboratory unit weight, unconfined compressive strength testing.  This project provides a useful case history of construction on the coral reef limestone and significant amount of experience of geotechnical investigation, coordination among different disciplines and different stake holders as well as practical execution of technical plans are accumulated.
