【文章內(nèi)容簡介】 置設(shè)置錨桿，，并且在拱墻、仰拱鋪設(shè)鋼筋網(wǎng)，在必要時要鋪設(shè)鋼拱架。二次襯砌：V級圍巖二次襯砌35cm,為曲墻式襯砌。三、圍巖壓力計算計算圍巖壓力的公式：。式中的為圍巖重度；為圍巖級別，V級圍巖=5； 圍巖豎向壓力q： 圍巖水平壓力：四、襯砌內(nèi)力計算： 襯砌單元劃分 圍巖壓力根據(jù)工程類比法采用:初襯20cm厚,二襯35cm厚。本設(shè)計采用結(jié)構(gòu)力學(xué)的彈性鏈桿法進行內(nèi)力計算，運算過程采用FORTRAN語言編寫的程序。由《鐵路隧道設(shè)計規(guī)范》可知，單線電氣化鐵路在進行節(jié)點化分時，要不少于16個單元，在本設(shè)計中，把V級圍巖襯砌劃分為22個單元,。 襯砌計算參數(shù)節(jié)點數(shù)(個)23襯砌容重(kN/)23襯砌彈性模量(GPa)28水平荷載(kN)豎向荷載(kN)水平彈性抗力系數(shù)(MPa/m)200豎向彈性抗力系數(shù)(MPa/m)200墻角支座寬度(m) 計算輸入數(shù)據(jù)結(jié)點數(shù)襯砌x坐標(biāo)(m)襯砌y坐標(biāo)(m)彈性支撐約束水平約束豎向約束轉(zhuǎn)角約束襯砌單元厚度（m）110112011130111401115011160111701118011190111100111111111121111131111140111150111160111170111180111190111200111210111220111231011用FORTRAN程序計算襯砌內(nèi)力如下： 數(shù)據(jù)輸入格式()： 23 23 1 0 1 1 0 1 1 1 0 1 1 1 0 1 1 1 0 1 1 1 0 1 1 1 0 1 1 1 0 1 1 1 0 1 1 1 0 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 0 1 1 1 0 1 1 1 0 1 1 1 0 1 1 1 0 1 1 1 0 1 1 1 0 1 1 1 0 1 1 1 0 1 1 1 1 0 1 1 襯砌內(nèi)力輸出()：1STEP NO.
