有一天半夜，面對著諾斯特拉達穆斯的預言詩，我正愁著不知如何翻譯其中的幾句，心中想到師父，師父就突然打電話來了，最後還問我有沒有什麼問題，我就藉機請問她。 -
In light of the simulative research results, three methods are applied to analyze some controversial problems in this kind of structural system ( such as the concrete pouring sequence of continuous ends, the applying sequence of pretensioned force, the removal of the temporary supports, the concrete pouring style of continuous ends, the optimization of constructional reinforcement and prestressed reinforcement ). some important conclusions are drawn : the concrete pouring sequence of continuous ends should be in accordance with the principle of " interval end " ; the removal of temporary supports is also on this principle ( opposite to traditional opinions ). at the same time, other problems such as the shrinkage and creep effects of concrete, the c racking and failure pattern, the optimization of reinforced bars and prestressed bars are also analyzed in detail
在此基礎上，對于目前先簡支后連續結構體系中存在的一些有爭議的問題（如后連續端部澆築和后連續預應力張拉的順序、體系轉換中的臨時支座拆除順序、后連續端部澆築方式、后連續端部的預應力筋及普通鋼筋的優化等） ，我們分別運用三種方法進行了細致的模擬分析、研究，並得出了一些具有重要工程意義的結論：后連續端部的澆築順序和后連續預應力張拉的「隔跨」原則，臨時支座拆除的「隔跨」原則（此前人們一直認為「對稱澆注和對稱張拉」是最為合理的施工工序） ，混凝土的收縮、徐變對先簡支后連續結構體系的影響一般較小等。
