摘要
基坑的安全影响着后续施工的进程和安全,故通过对基坑坡顶部分土体的沉降量和邻近相关建筑物的沉降量进行持续性的监测。结果表明:随着基坑开挖的期间段以及在开挖到底之后的一段时间内,基坑坡顶土体和周边建筑物的沉降量增加明显。并随着开挖完成时间的增加,基坑的沉降量变化很小,土体几乎达到稳定状态。
The excavation of the foundation pit has a greater threat to the safety of the foundation pit itself and the surrounding buildings.For the purpose of foundation pit safety,the settlement of the foundation pit slope and the horizontal displacement of the surrounding buildings of the foundation pit are detected.Analyze the settlement of the surrounding measurement points of the foundation pit and the settlement of the surrounding buildings using a level gauge and through the data measured on the spot.The results show that the soil on the top of the foundation pit slope is The settlement of surrounding buildings and surrounding buildings has increased significantly.After a period of time after the excavation of the foundation pit,the settlement of the surrounding soil and surrounding buildings reached a stable state.
