摘　　要：以西安某地万达广场基坑沉降监测为例,结合沉降监测的相关理论,首先介绍了广场基坑沉降的实测方案,然后对沉降监测数据进行了处理分析,最后基于回归模型对沉降趋势进行了预测,并将预测值与实测值进行了对比分析,二者残差较小,验证了回归分析模型在广场基坑沉降预测中的可行性。Taking the foundation pit settlement monitoring of Wanda Plaza in Xi'an for example, combining with the relevant theories of settlement monitoring, we introduced the settlement monitoring plan of square foundation pit at first. And then, we processed and analyzed the settlement monitoring data. Finally, we predicted the settlement trend based on the regression model, and compared the predicted and measured values. The result shows that the residual is small, which can verify the feasibility of the regression model in the settlement prediction of the square foundation pit.
