The cutting method , installation and welding technique of the expansion joint of spiral case of no . 5 generating unit of long - tan hydropower station have gained good effectiveness , which can be used for reference for the similar generating unit 龙滩水电站安装完毕的5号机蜗壳凑合节的下料方法、安装与焊接工艺都取得了良好的效果，对同类机组会有一定的借鉴作用。
Results of the study are detailed as follows : firstly , relevance analysis is conducted to the record of the xiangjiaba project slope rock mass rheological test , using the technique of information gain of ms analysis services 应用msanalysisservices决策树数据挖掘模型的信息增益技术，基于龙滩水电站边坡岩体室内岩石流变试验数据进行相关性分析，研究了室内试验过程中各因素对岩石变形的关联程度。
Aiming at mulongtan hydropower station , this paper introduces the meaning of and protection about the temperature of hydro - generating units , the system composition , the configuration and work elements of sensors anti instrument , the means of realization with plc for temperature protection , and puts forward several measure of enhancing the temperature control system 摘要水轮发电机组温度的监测是机组安全运行的重要保证，是水电站计算机监控系统监测的重要参数，介绍了木龙滩水电站水轮发电机组温度测量和温度保护系统的一般组成模式，测温传感器、仪表的配置与工作原理，及采用plc实现温度保护的方法，并提出了提高温控系统可靠性几点措施。
During the construction of the diversion tunnel for longtan hydropower station , relevant construction and management techniques are applied ; by which the schedule , quality , safety and cost of the construction concerned are all under the controlled condition , and therefore , the realization of the construction target is guaranteed 摘要龙滩水电站导流洞施工采用了科学的施工与管理技术，使施工项目的进度、质量、安全和成本处于受控状态，从而保证了项目工程目标的实现。
In the first part , we compute the site design flood of given design frequency ( 0 . 01 % . 0 . 1 % . 0 . 2 % and 1 % ) using the design flood hydrograph . then we get the design reservoir inflow flood of the same design frequency by the resultant discharge method . according to the computing value we compare the site design flood and design reservoir inflow flood of different time interval 本论文以广西红水河龙滩水电站为例，在第一篇中采用洪水过程线法计算了给定设计频率为0 . 01 、 0 . 1 、 0 . 2和1的坝址设计洪水，并利用合成流量法计算了相应设计频率的入库设计洪水。
