水工隧洞围岩的选择一般取决于隧洞过水量以及围岩所受压强的大小。本文从水工隧道的具体施工出发,以力学为分析工具,具体论述了围岩的选择与岩石抗力系数的具体关系。
水工隧洞圍巖的選擇一般取決于隧洞過水量以及圍巖所受壓彊的大小。本文從水工隧道的具體施工齣髮,以力學為分析工具,具體論述瞭圍巖的選擇與巖石抗力繫數的具體關繫。

The selection of hydraulic tunnel surrounding rock general y depends on the tunnel water yield and the pressure of surrounding rock. This paper starts from the concrete constr-uction of hydraulic tunnel, takes the mechanics as analysis tools and discusses the relationship between the selection of surrounding rock and rock resistance coef icient.
