With the development of high - technology, all trades " production and development need electric power which is one of the main energy. so the accuracy of electrical parameter caculation is very important for our country ' s economic development. the normal usage of ac indictor is very important for guaranteeing electricity ' s safety production and accuracy of electrical parameter caculation. now the area of domestic ac indictor has lots of shortcomings such as demanding many people synchronous proceeding, equipment operation complicacy and personnel error etc. so it can not demand the need of modern ac indictor checking
因此電參數計量的準確可靠，對保證我國經濟的發展至關重要。交流儀表的正常使用，對保證發供電的安全生產、電能計量的準確可靠、電參量量值傳遞的準確可靠，發揮著至關重要的作用。目前國內交流指示儀表領域存在需要多人同步進行、校驗設備多、操作復雜、人員誤差大和勞動效率底等諸多缺點，加之電工校驗臺技術等級低，已經無法滿足現代化校驗交流指示儀表的需要。 -
This paper deploys research about the damnification identify, employ capacity and reinforce technology with reason of double bend arch bridge through finding out disease position of construct and cause, colligating these result of the actual bridge detection and load test and analysis and research on the theoretics of damnification, and so on, despending on a lots of measure and means, finding out its present condition and checking structure internal force through choosing the proper mechanics model according as a lots of prototype information
本題以安徽省省道s310上k139 + 000處的大店崗橋為實例，從檢測入手，利用各種檢測方法和手段，了解雙曲拱橋的現行工況，並依據各類原型資料選擇合適的力學模型進行結構內力驗算，通過荷載試驗、理論分析等方法，查明結構的病害部位和形成原因，綜合實橋檢測結果和荷載試驗結果以及損傷理論的分析研究等等，展開對雙曲拱類橋型的損傷鑒定、使用能力和合理加固技術方法的研究。
