摘要
结合某工程实例,针对复杂地质条件下圆形超深基坑的特点,建立了一套信息化施工监测体系,并将其运用到工程实践。选择了合理的计算模型,运用数值反分析手段着重就圆形围护结构的变形和承压水的信息化监测进行了分析,并且根据实际情况进行了改进,取得了良好效果,实践表明,这种信息化施工监测体系是可行的。
Based on the project of a cylindrical deep foundation excavation, the informative supervision system for excavation construction and its application under complex geological conditions is introduced. Numerical back analysis and informative supervision is conducted by selecting a reasonable calculating model. Deformation of the retaining structure and variation of the deep confined water pressure induced by dewatering are monitored and analyzed in detail. According to the supervision data, the model is modified and the calculating result is reasonable. The example showed that the informative supervision system is feasible.
