  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

    本文的主要工作是：對國內外預應力鋼結構的發展歷史及現狀作了綜述和總結，指出當前預應力鋼結構工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范圍和特點；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，採用線性規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；對多次預應力最佳的施加次數作了分析，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作用，對上弦和腹桿基本不起作用；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作用，經濟效益好於局部布索。

  7. The improvement on the process of automatically measuring city buildings is one of the most important problems in the current aerial photographic measurement. an approach to measuring a city building based on its structure information is presented. a city building ' s ideal model is first represented by some independent parameters according to its structure information and some image variants which can induce model parameters are defined, and then the initial value of image variants are acquired by combining all kinds of information in the left and right images. finally the optimal location of the building is found for some certain criteria. an implementation of this method is illustrated on flat - roof and rectangular buildings in detail. the experimental results show that not only the method is more automatic than existing methods but also the precision of measurement can satisfy the acquirement of the current aerial photographic measurement, and confirm the method has a good developmental and applied potential

    提高城市建築物測量過程的自動化程度是目前航空攝影測量研究的主要問題之一.文中提出了一種基於結構信息的城市建築物測量方法.首先根據城市建築物的結構信息，用幾個相互獨立的參數來描述建築物的理想模型，並定義能推導出模型參數的圖像變量，然後組合利用左右圖像中各種信息獲得圖像變量的初始值，最後在一定準則下尋求城市建築物的最佳測量位置.該文以平頂矩形建築物為例詳細討論了它的一種實現演算法.實驗結果表明，這種方法與傳統方法相比較，有較高的自動化程度，且測量精度能滿足現有航空攝影測量的要求，有較大的發展和應用潛力
