摘要
以徐州市地铁市政府站为依托,给出了现场的监测方案并对现场的监测数据进行了分析,研究了基坑围护结构的变形规律、支撑轴力的变化以及周围土体的成像规律。同时,也对地铁站的施工进行了数值模拟,得到的数值模拟结果与现场的监测数据进行对比分析,最终证明徐州地铁市政府站采用的地下连续墙加水平支撑的支护结构是合理的,能够保证施工的安全。
Based on the subway station of Xuzhou City,this paper gives the monitoring scheme on and analyses the monitoring data,and studies the deformation law of the retaining structure of the foundation excavation,the change of the supporting axis force and the imaging law of the surrounding soil.At the same time,the paper also carries out the numerical simulation of the subway station construction.The results of the numerical simulation are compared with the monitoring data in the field.Finally,it is proved that the supporting structure of the continuous slurry wall and the horizontal bracing adopted by the Xuzhou subway station is reasonable and can guarantee the safety of the construction.
