围岩压力

利用ANSYS的参数化高级设计语言，编制了适合任意三心圆拱衬砌断面和不同围岩压力分布形式的隧道衬砌内力和偏心距的通用计算程序。

A general program using APDL ( ANSYS parametric design language ), which is applicable to arbitrary lining sections of the three-centered circular arch with different surrounding rock pressure distributions , was developed for the calculation of the tunnel inner forces and eccentricities .

所得到的塑性区应力、塑性区半径、围岩压力和硐室周边位移等研究结果，与基于理想弹塑性体的Fenner解答相比，要更接近实际硐室围岩中的对应量值。

The research results of plastic zone stress , plastic zone radius , surrounding rock pressure , and surrounding rock displacement are more nearly actual correspondence values of cavern surrounding rock with Fenner solution based on ideal elastoplastic materials .

以大型通用软件ANSYS为平台，采用静力等效原则，把压力转化为相应的节点荷载，解决了隧道围岩压力与节点位置相关又不与衬砌结构垂直的输入问题。

Based on the large-scale universal software ANSYS , the input problem that surrounding rock pressures of tunnel are associated with node location but not perpendicular to the lining was solved using static equivalent principle to transform the pressures into corresponding nodal loads .
