摘要
结合某工程实例分析了预应力张弦梁钢支撑体系的施工参数、施工流程及监测要点,研究预应力张弦梁钢支撑系统在深基坑支护中的应用效果,并和传统钢支撑系统进行对比,表明张弦梁钢支撑系统在施工空间、工期和造价上的明显优势。最后结合基坑监测数据,表明基坑沉降与变形控制在安全范围内。
Combined with a project example analysis of the pre-stress string joist steel support system construction parameter,construction process and monitoring points,the prestressed joist steel support a string system application effect in deep foundation pit supporting,and were compared with the traditional steel support system,show that piece of string joist steel support system on the construction of space and time limit for a project and cost of obvious advantages.Finally,combined with the monitoring data of foundation pit,it is shown that the settlement and deformation of foundation pit are controlled within the safe range.
