摘要

介绍了用变分法解决地下工程支架塌拱压力问题的各种方法。以里特方案为基础。根据岩土强度特征的 "护照"，描述了塌拱与周围土体之间的相互作用。大多数解都以封闭形式给出。通过极限分析方法获得的岩土中支座最大压力的数值计算结果接近理论值。

Variational Solutions for the Problem of Arching in Rock Soils

Variants of solving the problem of collapse arch pressure on the support of an underground work by variational methods are presented. Ritter’s scheme is used as a basis. The interaction between the collapse arch and surrounding soil mass is described based on the “passport” of strength characteristics for rock soil. Most of the solutions are given in closed form. The numerical calculation results obtained by the limit analysis method for the maximum pressure on support in rock soil are close to the theoretical values.
