摘要
以地球物理学的基本理论为指导,根据地球重力场的特点,探讨了地下采矿洞壁围岩侧压力的来源,提出了地下采矿围岩压力与应力计算的新方法,给出了坑壁及拱顶压力与应力的计算公式,坑壁侧压力计算公式为P=m(θ2-θ2)。
According to the basic theory of geophysics and characteristics of earth gravity field, the author probes into the source of lateral pressure of tunnel wall in underground mining. A new method of calculating the pressure and stress of surrounding rocks in underground mining has been advanced. It gives new calculation formulas of pressure and stress of tunnel wall and vault. The lateral pressure of tunnel wall in underground mining is P=m(θ2-θ1).
