某水工隧洞衬砌裂缝开度计算及裂缝机理分析

摘要

结合某水工隧洞衬砌所发生的裂缝情况，通过现场调查获取了第一手资料，并经过分析和计算，取得了水工隧洞衬砌裂缝开度计算及裂缝机理分析成果。计算结果与原型观测资料相比吻合良好。该研究对水工隧洞衬砌裂缝开度计算及裂缝机理分析具有参考价值。%In combination with the crack conditions occured in a lined tunnel the first-hand data are obtained via the in-situ investigation. The calculation results of crack width and analysis of crack mechanism on concrete lining of a hydraulic tunnel are achieved via the analysis and calculation. The calculation results tally with those of prototype observation. Accordingly,this research is of some reference value for the calculation of crack width and analysis of crack mechanism on concrete lining of hydraulic tunnel.
