由水电部西北电力设计院主持的“六十米跨度预应力钢桁架试验研究成果鉴定会”于三月上旬在昆明召开。出席会议的有来自全国三十二个单位的设计、施工、科研及教学等方面的四十六名代表。“六十米跨度预应力钢栈桥”是由西北电力设计院、哈尔滨建筑工程学院、宁夏自治区第二建筑工程公司及宁夏大武口电厂等四个单位共同协作完成的科研项目。会议听取了新结构的静力性能、动力性能、抗震性能、低温性能、锚具及预应力筋的性能等方面的试验研究报告,并观看了录象。与会同志经过认真充分地讨论,通过了“六十米跨度预应力钢桁架科研成果鉴定意见书”。
The “60-meter span prestressed steel truss test achievement appraisal meeting” hosted by the Ministry of Water Resources and Northwest Electric Power Design Institute was held in Kunming in early March. Attending the meeting were 46 delegates from the design, construction, research and teaching of 32 units nationwide. The “60-meter span prestressed steel trestle bridge” is a scientific research project jointly completed by four units including Northwest Electric Power Design Institute, Harbin Institute of Civil Engineering and Architecture, Ningxia Second Construction Engineering Company and Ningxia Dawukou Power Plant. The meeting listened to the experimental research report on the new structure’s static performance, dynamic performance, seismic performance, low temperature performance, anchorage and prestressed tendon performance, and watched the video. After serious and thorough discussions, the participating comrades adopted the “60-meter-span prestressed steel trusses research appraisal opinions.”
