摘　　要：归纳了国内外常用确定最小岩石覆盖层厚度的方法———挪威经验法、国内顶水采煤经验法、隔水岩柱经验计算法和日本经验公式,利用上述四种方法对重庆两江隧道中的长江隧道最小岩石覆盖层厚度进行工程类比分析得到,长江隧道最小岩石覆盖层厚度取值为21 m^32 m。The common methods of determining minimum rock covering thickness at home and abroad were concluded, which were Norwegian experience method, jacking water coal mining experience method in China, water insulation rock specimen experience calculation method and Japanese experience formula. The minimum rock covering thickness of Changiiang tunnel of two rivers tunnel in Chongqing were engineering compared and analyzed using above four methods, it can be got that the value of the minimum rock covering thickness of Changjiang tunnel is 21 m--32 m.

关 键 词：工程类比 水下隧道 最小岩石覆盖层厚度 取值范围
