APPLICATION OF GREY MODEL MGM(1,n) TO DEFORMATION MONITORING OF DEEP EXCAVATION

摘要: 变形监测在基坑开挖工程中具有重要意义。对于不同的监测点,选取若干相关联的监测指标,采用MGM(1,n)模型进行综合预测,体现出监测值之间本身的内在联系,具有更高的准确性和可信性。通过联合周围建筑物沉降和相邻的测斜孔位移进行分析预测,取得了较好的效果。Abstract: Deformation monitoring plays important role in excavation-engineering work.As to different monitoring spots,some relevant monitoring targets are selected.MGM(1,n) model,used to proceed a synthesizing prediction,embodies the inner relationship of the deformation data,so it must be much more veracious and credible.It is combined the settlement of nearby-buildings and the displacement of adjacent inclined holes.And the result of prediction is good.
