因此近年來，國內外工程界都在著力探討新舊混凝土的結合問題，但是比較完善、被大家公認的理論還有待探索。A huge actual constructions and tests has proved that the bonding power of the bonding surface is often too small to satisfy the actual stress, and that in the construction of the new to old concrete, the construction process is blind because there are no unified standards of the construction technology, which leads to the quality of the construction is inferior. and in the design process, the designers who can ’ t identify the strength of the bonding surface can not make an accurate, economic and proper design, which will lead to waste or engineering accident
大量的實際工程和試驗證明，結合面的粘結力通常比較小，往往難以滿足實際結構受力的需要，而且在新舊混凝土粘結的施工過程中，施工工藝沒有統一的標準，造成施工過程的盲目性，最終導致工程質量的低劣;在設計過程中設計人員不能判斷出粘結面的強度，這就使設計人員不能準確、經濟合理的做出設計，造成浪費或埋下工程事故的隱患。分享友人
