[提要] 對于超長的鋼筋混凝土結(jié)構(gòu)，需要在一定的長度處設(shè)置溫度伸縮縫，但地下室溫度伸縮縫的『卜水帶由于老化會引起漏水。故超長地下室采用微膨脹混凝土澆筑而不設(shè)溫度伸縮縫是一種經(jīng)濟、有效的措施。為此提出了相應(yīng)的簡化計算公式和設(shè)計建議。
[關(guān)鍵詞] 伸縮縫 膨脹混凝土 化學(xué)預(yù)應(yīng)力 地下室To the reinforced concrete structures with excessive regulation length, the usual method is designing a expansion joint in certain length. But the stopwater band in expansion joint of the basement will leak out water because of aging. Adopting tiny extended concrete to build the excessive regulation length basement without setting expansion joint for temperature is an economical and efficient design. The simplifying formulas and design suggestion are proposed.
Keywords: expansion joint; expansive concrete; chemical prestressed
