摘要
本文依据《水工隧洞设计规范SDB4—84》,将外水压力作场力处理,且注意到水荷载有着荷载历史这一特点,系统地讨论了水工压力隧洞含水围岩渗透水压力分布规律,建水了设集中排水的水工压力隧洞衬砌与围岩在施工期和运行期的弹塑性应力分析方法,给出了相应的解析计算公式。
According to 'The Design Standard SDB 4-84 for Hydraulis Pressure Tunnels' and Consider the Water pressure being field force, more over, the loading history of hydraulic pressure on the surrounding rock is taken into account. A thorough discussion on the pressure distribution is given in this paper. The writer presents a stress analysis method of tunnel lining and surrounding rock with concentrate drains under construction stage and operating period by elastoplastic theory .The corresponding Cal-culatrion formulars are recommended.
