There is special requirement to the testing technology for lining structure due to its specific characteristics. 由於地下工程襯砌結構的特殊性，對檢測技術具有一定的要求。
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。
