摘要
珊瑚礁类岩土是一种特殊的工程岩土,珊瑚礁岩不同于土,受压对变形不是颗粒的重新排列;也不同于一般岩石,一般岩石以弹性变形为主,珊瑚岩变形的重要组成之一是空隙的脆性压实。本文依托沙特某电厂工程实例,通过常规勘察、划分土层及静载试验阐述了珊瑚礁岩的工程特性,特别是地基承载力问题。珊瑚礁岩属非均质地基,高承载力伴随着不均匀性。同时,由于目前勘察研究较少,尚没有列入国家规范,其工程特性有待更进一步探讨。
Coral reefs class rock is a special project for geotechnical engineering.The coral reef rock is different with the earth,and bearing distortion is not a result of the pellet realignment.It is also different from the common rock,which generally give priority to the elastic deformation,and one of the most important compositions of distorts of the coral rock is the brittle compaction.The paper is based on an instance of a power plant project in Saudi Arabia,through routine reconnaissance,divide soil layer,and static load test expounding the engineering properties of coral reefs,especially bearing capacity.Coral rock is a non-homogeneous foundation,high-bearing capacity accompanied by heterogeneity.Sometimes,since the present investigation focuses,haven’t been included in the national standard yet,the engineering mechanics features still remain to be further discussion.
