摘要
通过灰色理论中的GM(1,1)模型,对软土地区基坑开挖后引起的地表沉降进行了分析预测,其预测结果与监测结果接近。结果表明,在GM(1,1)模型中,利用初期沉降位移实测值来预测未来一定时间内的沉降位移值能够得到比较准确的预测结果,因此对指导基坑开挖和支护具有一定的作用。
The GM（1,1） model in Grey theory was used to predict and analyze the ground settlement of foundation pit in soft soil area after excavation,and the prediction result is close to the monitoring result.The result shows that,in GM（1,1） model,correct prediction result can be obtained by using the measured values of initial settlement to predict the settlement in the certain time of the future,therefore,the prediction result can be of certain guidance to the foundation pit support and excavation.
