集团综合办公楼深基坑采用土钉支护和护壁桩支护两种形式,通过设计、施工和监测多环节的控制,从现场量测数据分析表明:基坑最大水平位移发生在基坑顶部;雨季雨水渗入土体使基坑水平位移增长较大;通过现场监控,及时作出必要的修改和采取必要的措施,确保了工程质量和施工安全。
The deep foundation pit of the group office building adopts two forms of soil nailing and retaining wall pile support. Through the design, construction and monitoring of multiple links, the analysis from on-site measurement data shows that the maximum horizontal displacement of the foundation pit occurs at the top of the foundation pit. Rainwater seeps into the soil to increase the horizontal displacement of the foundation pit; through on-site monitoring, necessary changes are made in time and necessary measures are taken to ensure project quality and construction safety.
