摘　　要：根据三山岛金矿海底开采工程概况,调查分析了国内外开采沉陷与建筑安全评价的研究进展。在进行岩石力学实验和构造应力分布规律测量的基础上,根据岩层与地表移动机理,进行了开采状况的三维建模和有限元分析,得出了开采沉陷与建筑安全评价的几个重要参数。结合国家建筑损害评价等级标准,评价了海底开采对滨海建筑的影响状况,并提出了控制措施。Based on the undersea mining in Sanshandao gold mine, the mining subsidence and building safety evaluation at home and abroad is investigated. With rock mechanics tests, tectonic stress measurement and rock moving mechanism analysis, a 3D model of mining situation is established and some finite element analysis is carried out. Several important indices are obtained for mining subsidence and building safety evaluation. Combining with national building damage evaluation standard, the influences of undersea mining to the nearby buildings are evaluated. Some controling measures are put forward as well.
