  大體積混凝土結(jié)構(gòu),體積巨大,通常不配置鋼筋,由混凝土本身承受拉應(yīng)力。拉應(yīng)力主要由溫度變化引起,因此控制溫度應(yīng)力是大體積混凝土結(jié)構(gòu)設(shè)計(jì)和施工的一個(gè)重要問(wèn)題。以混凝土壩為例,體積巨大,分層施工,建造周期長(zhǎng)達(dá)數(shù)年,受環(huán)境溫度變化和施工過(guò)程影響,壩體溫度應(yīng)力變化十分復(fù)雜,過(guò)去無(wú)法計(jì)算,實(shí)際上是“無(wú)壩不裂”?!洞篌w積混凝土溫度應(yīng)力與溫度控制》介紹了作者建立的混凝土溫度應(yīng)力和溫度控制的完整理論體系,包括重力壩、拱壩、水閘、船塢、隧洞、澆筑塊、地基梁等各種大體積混凝土結(jié)構(gòu)溫度場(chǎng)和應(yīng)力場(chǎng)的精細(xì)計(jì)算方法,控制溫度防止裂縫的技術(shù)措施和設(shè)計(jì)與施工準(zhǔn)則。在該理論指引下,我國(guó)已在世界上首次建成數(shù)座無(wú)裂縫混凝土壩,證明這一套理論是正確而切實(shí)可行的。在壩工技術(shù)上取得了比較重要的成就,曾先后獲得國(guó)家自然科學(xué)獎(jiǎng)、國(guó)家科技進(jìn)步獎(jiǎng)和國(guó)際大壩會(huì)議榮譽(yù)獎(jiǎng)。
