根据岩石和围岩的蠕变机理以及软岩流变控制原则,建立海域第三系软岩巷道围岩蠕变最优支护计算方法,求出软岩支护的两个重要参数,即最优(小)支护力和围岩最大允许变形量。 According to the creep mechanism of rock and surrounding rock and the principle of soft rock rheology control, the calculation method of optimal creep support for surrounding rock of Tertiary Soft Rock Roadway in sea area is established, and two important parameters of soft rock support are obtained, Excellent (small) support force and the maximum allowable deformation of surrounding rock.
