摘要
对相关规范中监测项目、监测方法和深基坑事故破坏形式统计分析,得出深基坑集约化监测项目的一些简单结论:围护墙(坡)顶水平位移;放坡、喷锚、土钉墙支护时围护墙(坡)顶竖向位移;一级基坑或悬臂支护时围护墙体内力;一、二级基坑工程的深层水平位移、支撑轴力和软土地区坑底隆起;地下水位,周边地表竖向位移和特定因素下孔隙水压力为深基坑集约化监测项目。锚杆拉力和土体分层竖向位移不作为深基坑集约化监测项目。
Based on statistical analysis of monitoring items,monitoring methods and deep foundation excavation accident damage forms,this paper draws some simple conclusions of layout of internal control intensive monitoring items for deep foundation excavation.The intensive monitoring items includes horizontal displacement of retaining structure,vertical displacement under specific factors,internal force under the first-level of security level and cantilever supporting,strut axial force,bottom heave in soft soil area,horizontal movement of depths soil under the first-level,second-level of security level,groundwater level,ground surface settlement and pore water pressure under specific factors.Anchor tension and soil vertical displacement aren't considered as intensive monitoring items.
