| 摘 要： | 通过对普氏、秦氏、太沙基及浅埋隧道地压公式的分析，提出了等效岩柱高度的概念，揭示了传统地压公式可以归结于等效岩柱高度和重度的乘积而具有的本质统一性，并给出了考虑营运修正系数的统一地压表达式。最后结合工程实例，验证了统一地压公式的正确性。

| Abstract: | Considering a correction coefficient of ground pressure of tunnel in operation, a unified formula containing a newly proposed concept, equivalent rock height, for calculating tunnel or underground gallary pressure were put forward through a serial of analyses of traditional principles of tunnel pressure. Finally, in situ measurement of a certain road tunnel was compared with those results calculated with some empirical formulae, the newly proposed formula proves correct. |
