Following the enlargement of the dip angle of the rock structure of the pressure of the surrounding rock and the internal force of the lining structure increase all the time. 最後詳盡地闡述了在不同岩層傾角狀況下，圍岩壓力與襯砌結構內力分佈特徵，即圍岩壓力與襯砌結構受力隨岩層傾角的增大而增大。
Redistribution of internal force and deformation of structure will bring lots of disadvantage factors to structure construction during structure construction. 施工期間出現的結構內力重分佈和形變給結構施工帶來諸多的不利影響。
