摘要
为了对滩子口水库拱坝的安全级别进行鉴定,首先在拱坝坝身和左右重力墩现有病害现象的基础上,运用拱梁分载法分析研究了拱坝坝身和左右重力墩存在的病害及其产生的原因。研究成果表明:该拱坝体型设计不合理和施工质量差是病害产生的主要原因,大坝被鉴定为病险严重坝,需要整治加固。然后根据病害成因研究了整治措施及设计方案。最后,通过整治处理后大坝的观测与检查结果分析,大坝目前运行良好,未见渗漏,渡汛亦安全,大坝的病害成因分析及整治措施的设计是合理的。
In order to evaluate the dam safety of Tanzikou reservoir, the arch dam and its gravity abutments on the left and right sides of the reservoir have been studied to ascertain the defects and the main reasons causing the defects. Results indicate that defects do exist due to irreasonable designs and poor construction quality of the arch dam. On the basis of the reasons causing the defects of the arch dam, treatment measures and design proposal have been put forward in this study. Results of the observation and inspection after the treatment of the dam have justified the feasibility of the treatment measures. Furthermore, a satisfactory operation of the dam has been obtained.
