By analyzing the case of deep excavation of shanghai urban planning exibition center , some deflection controlling measures and principles were illustrated by use of the top - down excavation method 摘要結(jié)合工程實例來探討逆作開挖條件下控制深基坑卸載變形的方法、原理和技術(shù)。
The deflection ' s control is very important during the cantilever ' s construction . but the re - distribution of strain and inner force causing by creep caused difficulty to the deflection control 在懸臂施工中,撓度的控制是施工成功與否的關(guān)鍵之一,而徐變引起的變形及內(nèi)力重分布是撓度控制的一個難點。
It is pointed out that wind vibration comfort control on tall steel structure by using modem control technique and the lateral deflection control on the frame - core wall structure by using outriggers can be realized 指出了現(xiàn)代控制技術(shù)對高層鋼結(jié)構(gòu)風(fēng)振舒適度控制及外伸臂對框架核心筒結(jié)構(gòu)體系水平位移指標控制的實現(xiàn)。
