摘    要：按岩体结构观点对隧道围岩进行分类,将其分为连续介质围岩、碎裂介质围岩、块裂介质围岩和板裂介质围岩等类型,其中碎裂介质围岩、块裂介质围岩和板裂介质围岩合称为破碎围岩,进而确定不同类型破碎围岩中隧道荷载计算的力学模型,求出了破碎围岩中隧道荷载计算的理论解,并将板裂介质围岩中隧道荷载理论运用于实际工程的计算。结果表明,计算值与实测值较吻合。

Abstract: According to the point of rockmass structure, a new rockmass classification method is proposed, i.e.rockmass is classified into continuous rockmass, broken rockmass, block rockmass and sheet broken rockmass.Their related mechanical models of single tunnel are determined and theoretical results of tunnel load inside poor quality rock mass are also obtained .The theoretical results of sheet broken rockmass in single tunnel is in agreement with the experiment results.
