《南水北调与水利科技》：浅谈泵站进水流道大体积混凝土裂缝的预防和控制（韩仕宾,戴敬秋，陈卫东）（摘要）

摘要：泵站进水流道多为大体积、变截面异型混凝土结构，施工中最常见的质量缺陷就是混凝土裂缝问题。结合南水北调东线第一期工程解台泵站进水流道的施工，着重阐述流道大体积混凝土裂缝预防和控制的措施，旨在为南水北调东线江苏境内工程和南水北调类似工程提供经验和借鉴。

Abstract:The inlet conduits in pump station are almost large volume and variable cross-section abonrmal structures.Concrete cracks are the normal quality defects in the course of construction.Based on the construction of the Xietai pump stations inlet conduit of the first ERP,the measures on precautions and control against large volume concrete cracks were analyzed.Experience here can be used for the eastern route projects in Jiangsu province and the similar projects of South-to-North Water Transfer.
