摘要
以某建筑深基坑工程为例,介绍了土钉墙在基坑深度大、土岩组合地层、坑壁陡峭条件下的设计应用,并采用智能监测云平台实现变形的实时监测和预警推送。结果表明,该工程的支护结构设计合理,边坡稳定性验算满足要求,各项变形指标均小于变形控制值。本项目对深基坑支护结构设计和智能化监测有一定借鉴。
The design application of soil nail wall under the conditions of large depth of foundation pit,soil-rock combination stratum,and steep pit wall was introduced,and an intelligent monitoring cloud platform was used to realize real-time monitoring and early warning push of deformation.The results show that the support structure of the project is reasonably designed,the slope stability verification meets the requirements,and the value of each deformation index is less than the deformation control value.This project has certain significance for the application of deep foundation pit support structure design and intelligent monitoring.
