  2. In view of the rapid development of electric undertaking and a sharp increase of steel products consumption, the state development planning commission, the former state water resources and hydropower ministry and state energy ministry have been urging that the building of steel towers should be strictly controlled in the construction of transformer substations ; and warning that the need of the present 500kv power transmission and transformer trusses can hardly be satisfied by ordinary steel and concrete electric poles or prestressed concrete poles, which have endangered the operation and longevity of the high voltage transmitting line due to the common problem of cracks by gravity

    隨著電力工業建設的迅速發展，鋼材的用量急劇增長，為此，國家計委，原水電部和能源部一再強調在輸變電工程建設中，應從嚴掌握自立式鐵塔的建設。然而，一般的鋼筋混凝土電桿或與預應力混凝土電桿，較普遍地存在著縱向裂縫問題，嚴重影響了高壓輸電線路的安全運行及其使用壽命，已不能適應高壓輸電桿塔和變電構架的要求。
  3. Now, these zones have become the best examples of the fastest development, the highest efficiency as well as the best economic growth, the true development poles in local economy. compared to the " first establishment " of chinese high - tech industrial development zones, internal and external factors contributed to the " second establishment " of chinese high - tech industrial development zones have great changed. for example, domestic market has transfer from supply market to demand market

    然而，與高新區「一次創業」時相比，現在的「二次創業」的內外條件發生了很大的變化，比如，國內市場，由賣方市場向買方市場（即稀缺到飽和）轉變；高技術企業的技術接受力，由低到高，進而向作強的方向轉變；現在企業技術的發展，不但要考慮技術的兼容性，而且還要給技術的發展保留一定的技術儲備； wto規則，要求政府的政策，對于國內外企業要一視同仁，原來的差別優勢和政策扶持，也不得不大范圍的趨同。
  4. But some enterprises lack systematic thought in informative construction, especially for those enterprises which are now in the transitional phase to flat structural system, they often dismissed the phenomenon that the middle - level contradiction shifts to the two poles therefore a lot of information block in the middle - level, all these greatly obstructed the development of enterprise informative construction

  5. 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。
