大坝溢流面贯穿性裂缝原因分析及处理

Reasoning analysis and disposal of a crevice running through Shangyoujiang dam

上犹江水电厂大坝检查廊道庚坝段顶拱有一条通长裂缝,局部已贯穿至溢流面。雨天及泄洪时产生渗漏。在分析原因的基础上,采用改性环氧树脂材料进行了灌浆处理,消除了渗漏,恢复了结构的完整,保证了大坝安全。

Reasoning-analysis and disposal of a crevice running through ShangYouJiang dam by routine security check,a long crevice running through arch of Shang YouJiang dam was discovered.The crevice is pratly so penetrate to flooding transverse section.Infiltration is happened during raining day and flooding discharge season.This paper aimed at reasoning-analysis,providing a pragmatic way in which epoxy-colophony is being used as material for grouting--disposal for the sake of avoiding infiltration.Consequently the integrity of the dam is been restored and safety of the dam is ensured.
