摘要
地下大空间开挖以后,上覆岩层发生离层,各岩层层板之间发生相互作用,而且岩板又可以看作薄板来考虑,因此就可以采用经典弹性力学建立三维叠合板模型并研究地下大空间的上覆岩层的分布规律,计算出多层叠合板岩层的挠度及其离层量的大小.
After underground excavations, the overlying strata separate and interact, as well as the strata can be considered as lamella. In this case, an establishment of the three-dimension superposition model and a study of the distribution of the layer separation in overburden should be taken into account, and a calculation of the deflection of the thin plate and the value of the separation should be made.
