三峡工程和向家坝水电站升船机船厢室结构 设计对比及质量控制难点分析

三峡工程和向家坝水电站升船机船厢室塔柱结构高度分别达到146 m和153 m，属于高耸结构，但又不同于一般的民用高层建筑，其设计标准与风荷载、温度荷载取值、抗震设计、船厢的埋件设计、测量及施工控制精度等都是无规范可循。因此，两个升船机在设计、施工过程克服了较多技术难题，也积累了丰富的建设经验。本文通过两个升船机的设计异同及质量控制措施分析，为将来同类型升船机建设提供有益的借鉴。

Comparison between ship-chamber structural designs of ship-lifts for Three Gorges Project and Xiangjiaba Hydropower Station and analysis on difficulties of their quality controls

The tower structures of ship-chambers for both the ship-lifts of Three Gorges Project and Xiangjiaba Hydropower Station reach to 146m and 153m respectively， which belong to high-rise structure， but are different from the conventional high-rise civil buildings. For their constructions， no any technical specifications or criteria are there to be followed by the design standards， the wind and temperature load value selections， the design of the embedded parts for the ship-chamber， the control accuracies for survey and construction， etc. Therefore， not only many technical problems are overcome during the design and construction of the ship-lifts， but rich construction experiences are also accumulated therein. Through the analyses made on the similarities and differences of the designs for both the ship-lifts as well as the quality control measures， some beneficial references are provided herein for the construction of the similar ship-lift in the days to come.
