  2. The main work of this paper was as fellows : ( 1 ) generalized the development of pre - stressed steel structure in our nation and abroad, and pointed out the main problem in practice ; ( 2 ) presented the mechanism of pre - stressed steel structure and revealed its applicable range ; ( 3 ) established the optimization design model for pre - stressed steel structure, which accounts for constraints on stresses and displacements of structure ; ( 4 ) brought forward the optimization design method, which combined linear programming and the principle of full restriction, through which we can obtain the magnitude of each time pre - stress and the optimized sections of each members of structure ; ( 5 ) analyzed the best times of pre - stress and pointed out that 2 ~ 3 times is preferable ; ( 6 ) conducted optimization design on large - space steel roof, horizontal parallel steel truss with local cables, horizontal parallel steel truss with global cable, and ultra - static steel truss, the result of which indicated that the multiple pre - stress structure is very economic ; ( 7 ) compared different schemes of cable placement for horizontal parallel steel truss, and the results showed that the local cable only unloaded the second girders, but had no response on the first girders and stomach poles, while global cable could unload the second girders and the stomach poles outside of turning point of cable, thus proving that global cable is more economic than local - cable

    本文的主要是:對國內外預應力鋼結構的發展歷史及現狀了綜述和總結,指出當前預應力鋼結構程實踐中存在的主要問題;闡述了預應力鋼結構的受力機理,並指出預應力鋼結構的適用圍和特點;在考慮結構應力和變位約束的條件下,建立預應力鋼結構優化設計模型;提出多次預應力鋼結構優化設計方法和步驟,採用線性劃和滿約束準則相結合的優化方法,可優化設計出施加的每一級預應力的大小,並得到結構各部分的優化截面;對多次預應力的施加次數了分析,並建議以2 3次為宜;為驗證文中理論和方法,分別對大跨多次預應力鋼屋架、局部布索的水平平行弦鋼桁架、整體布索的水平平行弦鋼桁架和局部布索的超靜定鋼桁架等算例進行了優化設計,經濟效益明顯;對水平平行弦鋼桁架的幾種施加預應力的方案進行比較,對于局部布索,預應力只對下弦起到卸載用,對上弦和腹桿基本不起用;而整體布索預應力除對下弦卸載外,對索折點以外部分腹桿也起到卸載用,經濟效益好於局部布索。

    通過試驗研究主要得出如下認識:沖擊壓實技術處理濕陷性黃土地基時,其有效處理深度一般不超過80cm ,沖壓遍數以30遍左右為宜;對路基分層沖壓,在要求土體中各點壓實度均達到要求時,路基沖壓組合為虛鋪厚度80cm 、沖壓40遍;在只要求土體平均壓實度達到要求時,路基沖壓組合為虛鋪厚度80cm 、沖壓30遍;大面積施時,質量控制方法可按照在以沖壓遍數為主要控制指標的同時,要求後10遍分計沉降量小於累計沉降量10 ;在施單位自己購置沖擊壓實機情況下,與傳統施相比較,沖擊壓實技術是一種既能節約資金又能大量縮短期的施方法。
