| 摘 要： | 从变形与位移的角度来考察基坑稳定性可以避开繁琐复杂的理论分析和计算工作,快速有效地对基坑工程的稳定性进行预测。建立了预测基坑周边地表沉降量及基坑稳定性的BP网络模型,并推导了求算基坑周边地表沉降量的估算式。结合具体工程实例对建立的网络模型和推导的估算式进行了验证,并对两类方法的求解条件、预测精度及适用范围等进行了比较说明。

| Abstract: | Analyzing foundation pit engineering's stability from the point of view of deformation and displacement can avoid the complex theoretic analysis and calculation so that the stability forecast of foundation pit engineering can be quickly and effectively made.A BP network model for forecasting the ground settlement around the foundation pit and foundation pit stability was established,and an evaluation formula to calculate ground settlement was deduced.Through of case study,the BP network model and evaluation formula were also verified,and the solving condition,forecast precision and applicability of the two methods were compared. |

| Keywords: | Foundation pit engineering Stability Ground settlement BP network Evaluation formula |
