According to the municipal engineering construction the characteristics of deformation monitoring, through five period with precision WanJi·OuJun of qingtian county retaining walls estate horizontal displacement and subsidence data results, the design is mainly through the field, the county to WanJi manor retaining wall in the construction stage to wall (slope) of deformation observation. In the deformation analysis process, choose the level of horizontal displacement monitoring data and the analysis of the data test. First data are singular value inspection, next to the deformation data periodic never get periodic data for the original data of the comparison of the interpolation method, and finally with the polynomial regression and grey system analysis of two methods of data fitting and predictions. In precision evaluation through the situation, for the next issue of deformation forecast and achieve high precision, that the method is correct and reliable. For the whole of the retaining engineering displacement and stability for preliminary analysis, to further perfect design theory and construction technology to provide information. Key words: Retaining wall; Deformation monitoring；Stability analysis 目 录 绪论 1 1 概述 2 1.1 变形监测的内容、目的和意义 2 1.2 变形监测技术和发展趋势 3 2. 青田万基·欧郡庄园挡土墙变形监测技术设计书 5 2.1 任务来源 5 2.2 监测目的 5 2.3 监测区概况 5 2.4 作业技术依据 6 2.5 监测点的观测方法和周期 6 2.6 监测控制网的建立 7 2.6.1 平面监测网的布设 7 2.6.2 平面监测网的施测 7 2.6.3 四等、一级GPS控制测量主要技术指标 8 2.6.4 青田县万基
