| 1. | Analysis of mechanism of jointed energy dissipation of stilling basin and aerated baffle and its validation by experiment 掺气分流墩与消力池联合应用消能机理分析与试验验证 |
| 2. | The correction factor of the pressure of cross section before a hydraulic jump in stilling basins under nappe flow of stepped spillways 跌落水流时台阶式溢洪道消力池跃前断面压力修正系数 |
| 3. | The t type barrier stilling basin has developed to a new energy dissipation technology which is adapted for energy dissipation of underflow in recent years T形墩消力池是近年来发展起来的新型消能技术,适用于底流消能形式。 |
| 4. | However , there are still not enough researches on the energy dissipation characteristics of the t type barrier stilling basin now . many problems existed still needs further study 但目前对t形墩消力池消能特性的研究还不完善,许多问题有待进一步研究。 |
| 5. | ( 5 ) lowing down the dam body will reduce the digging deep of the stilling basin , decrease the velocity of flow on the dam body and cut the difficulties of 但下游河床的冲刷加大,防护工作增加。降低坝体可以减小消力池的挖深,降低坝面流速和坝面的防护难度。 |
| 6. | The paper also introduced the applied situation of the actual projects about the t type barrier stilling basin through the helong reservoir spillway ' s hydraulic model experiment 本文还通过河龙水库溢洪道水工整体模型试检,描述了t形墩消力池在实际工程中的应用情况。 |
| 7. | To use the athwart gradient protection which takes the end of dam as the datum mark will reduce the digging depth of the stilling basins is reducing , and increase the energy dissipation rate 采用以坝体末端为基准面的坝体逆坡防护时,消力池挖深减小,消能率提高,坝面平均流速减小,坝区防护难度降低。 |
| 8. | It makes the t type barrier and continuous end sill connected . by this method , it can produce forced jump dissipation of energy . as a result , it decreases the length of the stilling basin and lows the cost T形墩消力池是在平底消力池内,设置t形墩与连续尾坎相连接,借以产生强迫水跃进行消能,从而减小消力池的长度,降低造价。 |
| 9. | The programe used optimization validate whether the design on energy dissipation and erosion prevention of cofferdam and dam is in reason , and it can campare the results from different projects to sellect the best one . ( 1 ) calculate the stilling basins " dimension 该优化计算程序能够验证围堰和坝体过流的消能防冲初步设计的合理性,并可以通过比较不同方案的计算结果,对消能防冲的初步设计进行优化。 |
| 10. | Firstly , according to the characteristics of the relative knowledge during the course of designing stilling basin , a new expression method of knowledge - object - oriented expression method has been designed after many usual expression methods of knowledge has been analyzed and compared with 首先,针对消力池设计专家系统中知识的特点,在研究、分析、比较多种知识表示方法的基础上,设计出适合于消力池设计的知识表示方法? ?面向对象的表示方法。 |
