（甘肅工業(yè)大學建筑工程學院 蘭州 730050）[提要] 結(jié)合甘肅省自行車賽場跑道下磚房墻體大面積開裂的實際工程，經(jīng)現(xiàn)場測試和分析，確定了裂縫產(chǎn)生的原因，計算了墻體中由于溫度引起的主拉應(yīng)力和賽道下磚房由于溫度變化引起的賽道與磚墻之間及構(gòu)造柱與磚墻之間產(chǎn)生的膨脹差，結(jié)果證明這些裂縫是由溫度引起的，排除了沉降產(chǎn)生裂縫的可能性，并由此給出了磚混結(jié)構(gòu)的1些抗裂設(shè)計建議，供設(shè)計人員參考。
[關(guān)鍵詞] 自行車賽場 跑道下磚房 墻體裂縫分析 處理Combined with the brick wall crack under the track of the cycle racing arena for Gansu province, and after the test and analysis, reason of the crack is determined. The main pull stress of the wall that is caused by the temperature difference between the track and the brick wall and the expansion difference between structure column and the brick wall is calculated. Some suggestions of the resisting remperature crack design about brick and concrete structures are given that may be reference to designers.
