某水库大坝基础帷幕灌浆施工方案研究

Study on Construction Scheme of Foundation Curtain Grouting for a Reservoir Dam

帷幕灌浆施工是防渗处理的主要施工手段,对水利建筑物的安全及有效运行起着关键作用。本文结合昆明市某水库大坝基础帷幕灌浆工程实例,通过对大坝基础的施工方案研究,以及在遇到特殊问题时的处理方法,阐述了在相类似的工程条件下对大坝基础帷幕灌浆施工工艺选取和应对措施,并对其工程的设计和施工提供一定的借鉴作用。

Curtain grouting construction is the main construction method of anti-seepage treatment,which plays a key role in the safetyand effective operation of water conservancy buildings.Based on the example of the foundation curtain grouting project of a reservoir dam inKunming,this paper studies the construction program of the dam foundation and treatment measures in case of special problems,expoundsthe selection and countermeasures of the curtain grouting construction technology under the similar engineering conditions,to providereference for the design and construction of the project.
