本文用边界元法分析了地下洞室的各向异性问题，推出了广义平面应变下边界积分的基本解。借助于节理及层状岩体的等效模量计算公式，将层状节理岩体内地下洞室问题转化为均匀各向异性问题求解，讨论了各向异性对地下洞室围岩应力及洞边位移的影响，并利用所编程序对自贡市十字口隧道进行了计算分析。显然，本文提出的解法可以推广应用于分嵖榫实母飨蛞煨晕侍猓阅Ｄ舛粗芰诮奈а姨匦院涂诘挠跋臁 In this paper, the anisotropy of underground caverns is analyzed by the boundary element method and the basic solution of the boundary integral under generalized plane strain is introduced. Based on the formula of equivalent modulus of jointed and stratiform rock mass, the problem of underground cavity in stratiform jointed rock mass is transformed into the problem of uniform anisotropy. The effects of anisotropy on the stress and cavity of surrounding rock of underground cavity Edge displacement of the impact, and the use of the program compiled Zigzag cross-mouth tunnel were calculated and analyzed.
