摘　　要：双排机水电站厂房布置型式是解决在高山峡谷段布置大容量多台数机组与场地矛盾的有效手段。文中以李家峡双排机水电站厂房为研究对象,对双排机厂房的结构分缝、不均匀沉降、温度场、上部双跨结构、深开挖对岸坡的影响以及结构抗震等一系列技术问题进行了深入研究。结果表明李家峡水电站双排机厂房结构设计合理,是一种值得推广的厂房结构型式。整个研究为后续的双排机厂房结构设计提供了可靠的参考。The structural array of powerhouse with double-row units arrangement may be an effective method which can settle contradiction between many high-capacity units and ground in narrow canyon. In this paper some key technical problems of Li Jiaxia hydropower house with double-row units arrangement are analyzed such as the structure joint, non-uniform settlement, temperature field, double span structure, the influence on bank slope during deeply excavating and structural earthquake resistance. According to the results of analysis. Li Jiaxia powerhouse is properly designed and this array can be used in other projects. The whole research can offer appropriate preference to structural design of new powerhouses with double-row units arrangement.
