纳子峡水电站面板堆石坝混凝土面板裂缝分析及处理措施

Analysis and Treatment Measure of Concrete Panel Crack of The “Na Zi Xia” Hydropower Station

面板裂缝处理是面板坝无法避免的一道工序,由于面板的综合防裂措施是一个复杂的过程,在施工过程中截止目前只能遏制裂缝发生的几率但从根本上无法消除裂缝产生的几率,纳子峡水电站混凝土面板堆石坝属于高寒、高海拔地区的面板堆石坝工程,由于所处的地理环境及气候条件相对于类似工程较为复杂,因此,在裂缝的处理方面也较为复杂,文章着重介绍了面板裂缝的处理措施,可为今后类似环境下的工程提供可借鉴的处理措施。

Plate dam is unavoidable for the panel crack processing, the procedure of comprehensive anti- cracking measure is very complicated. Nowadays, during the process of construction, the odds of crack occurrence can be only contained instead of completely eliminated, the ＂NaZiXia＂ hydropower station concrete slabs rockfill dam engineering happens at the cold climate and high altitude area. Compare with normal projects, the geograph- ical environment and climate of this engineering is more complicated, therefore, the treatment method for the cracks is intricate. This paper emphatically presents the treatment measures of panel crack, it aims at providing referential treatment measure for those engineering that happened at the similar environment in the future.
