（中南大學(xué)土木建筑學(xué)院，長沙410075）[摘要] 利用傳遞矩陣法分析變截面多孔沉井的受力和變形，將其簡化為變截面剛架，推導(dǎo)出了考慮軸力和軸向變形時變截面平面剛架結(jié)構(gòu)的場矩陣，并引入分支梁在分支點的傳遞矩陣。由于傳遞矩陣法是通過矩陣連乘求解的，精度比矩陣位移法高。

( School of Civil Engineering and Architecture, Central South University, Changsha 410075, China)Abstract: The transfer matrix method is used to analyze the force and deformation of variable cross-section porous caisson with reinforced ribs. Variable cross-section caisson was simplified to variable cross-section frame, and field matrix of variable cross-section plane frame structure considering the axial force and axial deformation was derived. Branch beam transfer matrix in the branch point was introduced. Because the transfer matrix method solves problems by matrix connected, its accuracy is higher than the matrix displacement method.
Keywords: variable cross-section porous caisson; transfer matrix method; force analysis; deformation analysis
