团结水库震损除险加固方案探讨

Discuss the Reinforcement for Tuanjie Reservoir damages after shake

为了对团结水库震损除险提出优化方案,对其在"5.12"汶川大地震震前和震后存在的病害进行了分析和计算。由于坝体表面主要病害为裂缝,用倾度法估算了坝体裂缝,并在应急开挖过程中对估算结果加以验证。运行情况和计算结果表明:该水库枢纽设计不合理、施工质量差和管理不当是病害产生的主要原因,震前大坝被鉴定为病险严重坝,震后被鉴定为高危水库,需要整治加固。根据病害表现及成因研究了合理的整治措施及设计方案,为类似工程的整治处理提供了参考。

This article analyzed and calculated the disease of the TuanJie reservoir before and after '5·12'Wenchuan earthquake for an optimized plan of getting rid of danger.For the chink as the major disease in dam surface,this article estimated the chink inside the dam by collapse degree then tested in the urgent excavation.Running conditions and calculation consequences indicate: the main causes of the disease reservoir are improper design,poor quality construction and mismanagement of the reservoir hub.The dam which had been identified as dangerous severe dam before earthquake,and high-risk reservoir after earthquake,needs reinforcement training.Then,basing on the causes of disease,the proper remediation measures and designs were researched giving a reference for similar project.
