摘要
文中以潍坊市客运枢纽站深基坑工程为例,分析了城市建筑支护方式的有效性,通过在基坑坡顶布置监测点的方式,监测各监测点的位移,以监测基坑的稳定性和支护的有效性。结果表明,各监测点的累计位移均未超过2.5mm,该深基坑较为稳定,支护方式能够适应该工程地质条件复杂,基坑较深等各种情况,取得了良好的效果。
Taking the deep foundation pit project of Weifang passenger transport hub as an example, this paper analyzes the effectiveness of the supporting structure of the project, and monitors the displacement of each monitoring point by arranging monitoring points on the slope top of the foundation pit, so as to monitor the stability of the foundation pit and the effectiveness of the supporting structure. The cumulative displacement of each monitoring point does not exceed 2.5mm. The results show that the deep foundation pit is relatively stable in the construction process, and the support method can adapt to the complex engineering geological conditions and deep foundation pit. After a variety of different soil layers and other conditions, good results have been achieved.
