摘要/Abstract

摘要： 对竖井开挖引起的地表沉降时间序列自相关系数的计算分析表明，这些时间序列具有非平稳性特征，即地表沉降量存在确定性趋势。对于竖井开挖引起的地表沉降，时间和空间是不可分割的两个变量，把沉降量的确定性趋势δ、时间t及空间x三者建立起相应联系，构建三者的函数关系模型：δ=f（x, t），使之能预测预报施工引起的地表沉降。

Abstract: The selfcorrelated coefficient of time and spatial variations of the ground surface subsidence induced by a shaft excavation is studied in this paper. It is concluded that the time series have nonstationary property, in other words, the subsidence of ground surface has a deterministic trend. For the ground subsidence induced by a shaft excavation, time and space are two independent variables, and the ground subsidence is a function of time and space. It is possible to predict the ground subsidence during the construction.

Key words: ground subsidence series, selfcorrelation coefficient, deterministic trend
