摘要
针对郑州某超期使用的深基坑支护问题,对基坑支护形式、超期使用时间、基坑周边环境做了初步调查,并对超期使用以来的基坑监测数据进行汇总分析;对变形较大区域和周边环境复杂位置进行力学验算。最后,对基坑安全等级给予评定,采取了相对应措施,取得了理想的效果。
Aiming at the overdue use problem of deep foundation pit support in Zhengzhou,a preliminary investigation of the foundation pit support type,the overdue use period and its surrounding environment is carried out.The monitoring data of foundation pit since overdue use are summarized and analyzed.The mechanical check is conducted on the complex location of large deformation area and surrounding environment.Finally,the safety level of the foundation pit is evaluated.The corresponding measures are taken and ideal results are achieved.
