摘要
根据隧洞施工期和运行期不同的受力情况 ,导出深埋隧洞塑性区不同的芬纳公式 ,确定无限大匀质体中轴对称圆洞的塑性范围 ,并给出公式的适用条件 .对算例的结果进行了芬纳公式修正前后的比较 .
In consideration of different loading conditions during the construction and operation of a tunnel, different forms of the Fenner formula and the conditions for application for different plastic ranges are derived to determine the plastic ranges of axially symmetric circular tunnels in infinite homogeneous bodies. A comparison of the calculation results by the modified Fenner formula and the original Fenner formula is also made.
