为了解释某些大跨度、高边墙地下厂房衬砌中存在的问题,如衬砌应力逐年增长的原因和岩体流变、混凝土徐变、温度变化等因素对衬砌应力的影响,本文编制了包括多种影响因素的非线性有限元分析程序,并利用该程序分析了某地下厂房钢筋混凝土衬砌的应力状态及各种影响因素对衬砌应力的影响.
In order to explain the problems in the lining of some large-span, high-sidewall underground powerhouses, such as the causes of the increasing lining stress year by year and the influence of rock mass rheology, concrete creep, temperature changes, etc. on the lining stress, this paper has compiled many A non-linear finite element analysis program for the influencing factors, and using the program to analyze the stress state of the reinforced concrete lining of an underground powerhouse and the influence of various influencing factors on the lining stress.
