小浪底水利枢纽进水塔群布置设计综述

Intake Towers Arrangement and Design Summarization of Xiaolangdi Key Project on the Yellow River

小浪底水利枢纽集中布置的十座进水塔一字型排列，各进水口相互错开形成了底位排沙、高位泄洪排漂、中间引水发电的布置特点。本文概述了根据不同塔架结构所采用的拟静力法抗倾覆、抗滑动非线性稳定分析，结构力学、三维有限元方法进行的静、动应力分析以及为验证分析计算的正确性所进行的抗震动力模型试验。

Xiaolangdi Multipurpose Project is a large controlling project on the Yellow River. The headwork of the structures for flood and sewage discharge, sediment flushing and power generation arranged concentratedly forms the rare intake towers in the dam construction history in the world, ten intake towers are arranged in a line and the intakes are at different levels, the bottom level for sediment flushing, top level for flood and floating debris discharge and middle level for power generation. This paper summarizes the nonlinear stability analysis against overturning and sliding in pseudo-static method, static and dynamic stress analysis in structural mechanics and three dimensional finite element methods, and the anti-Semitic dynamic model test to verify the correctness of analysis and calculation.
