【摘要】 在分析某洞库裂缝原因的基础上,采用间隔增设二次衬砌的方法对洞库进行了加固设计,提出了以控制原衬砌混凝土不出现裂缝的原则来确定二次衬砌间距的确定方法,并利用叠合构件位移协调的条件推导出了二次衬砌上荷载的计算公式,为洞库的二次衬砌加固提供了一套设计方法。更多还原

【Abstract】 Based on the analysis of crack causes for underground storage cavern structure,the methods according to the space were to added on the second lining in underground storage cavern.The calculation methods for determining the space between the second lining was putting forward by controlling the crack not existing in the original concrete lining,and the load calculation formula of second lining was reduced by using the compatible displacement conditions of composite members,put forward a design method reinforced the underground storage cavern by adding second lining.更多还原
