摘要: 岩溶作为一种特殊的工程地质现象,其发育程度的评价是工程设计的重点之一。根据黄石冶钢220kV变电站岩溶地基工程实例,将工程场地划分为若干个小区域,并采用Surfer软件绘制溶洞面密度等值线、场地基岩面三维等值线以及钻孔遇洞率等值线图,结合绘制图形与实际数据进行分析,对场地岩溶发育程度做出小区划评价,为工程优化设计提供依据。

关键词: 岩溶发育程度, 小区划, 评价方法

Abstract: As a special engineering geology phenomenon, the development degree evaluation of karst is one key of engineering design. Based on karst foundation engineering of Ye Gang 220 kV substation in Huangshi, the engineering site is divided into some small zones, and the surface density contour of karst cavity, three dimensional contour of bedrock surface, and drilling hole event rate contour are drawn by using software sufer. Based on the graphics and practical data the micro\|zoning of different karst development degree is evaluated, which provides reference for engineering optimization design.

Key words: karst development degree, micro\, zoning, evaluation method
