任庄水库大坝改建除险加固工程设计难点及先进技术简述

Brief introduction of design difficulties and advanced technology of dam reconstruction,danger removal,and reinforcement project of Renzhuang reservoir

任庄水库大坝改建除险加固方案成功的解决了原坝体存在的问题及隐患;成功的将左岸土基非常溢洪道改造成正常溢洪道参与泄洪;同时在土基溢洪道底板横缝设计中采用了齿槽互搭结构连接及底板锚固技术,为类似工程提供借鉴及技术支撑。

The reconstruction and reinforcement scheme of Renzhuang reservoir has successfully solved the problems and hidden dangers existing in the original construction;Successfully transformed the soil foundation extraordinary spillway on the left bank into a normal spillway to participate in flood discharge;In addition,the tooth and groove overlapping structure connection and bottom plate anchorage technology are adopted in the design of the transverse joint of the bottom plate of the earth-based spillway,which provides reference and technical support for similar projects.
