论文部分内容阅读
近来有些单位和读者来信要求我刊发表一些有关通航建筑物方面的知识和设计经验,但高坝通航建筑物在我国尚无建成实例,设计方面经验不多,参考资料也比较缺乏,长办设计单位也只是在结合三峡水利枢纽通航建筑物型式选择工作中,对两种主要型式(升船机和船闸)作了一些初步研究和综合工作。为了满足读者要求,这期先发表下面几篇文章,主要内容是介绍各种类型升船机的一般特性、优缺点,适应范围和存在的问题,并对高坝通航建筑物型式选择提出了一些认识。这对通航建筑物的选择比较,尤其是对升船机的研究有一定参考价值,今后对多级船闸型式选择比较也将作些系统介绍,供读者们参考研究。希对这方面工作有研完的读者们给我刊踊跃供稿。
Recently, some units and readers wrote a letter asking me to publish some knowledge and design experience on navigable buildings. However, there are still no examples of high-bay navigable buildings in our country, little experience in design, and lack of reference materials. The unit only made some initial research and comprehensive work on the two main types (ship lift and ship lock) in combination with the selection of navigable structures of the Three Gorges Project. In order to meet the requirements of readers, the following articles are published in this issue. The main contents are to introduce the general characteristics, advantages and disadvantages, adaptation scope and existing problems of various types of ship lift, understanding. This comparison of the choice of navigation buildings, especially for the study of ship lift has some reference value, the future will be more than the type of shiplock type selection will also be some of the system for readers to study. We hope readers who have finished their work in this field will give me an active contribution.
