摘要
对城市地面沉降分析中几个经常遇到的问题进行了讨论,提出了处理的方法。重点讨论了地面沉降数据处理中参考基准的稳定性以及如何使用变形分析的方法选择参考基准。认为地面沉降量只是一个参考值,并不是唯一的判定标准,提出了地面沉降漏斗的3个判定标准,并通过实例予以说明。
Several technical problems in ground subsidence analysis were discussed and some solving methods were proposed.We mainly explored the stability of reference benchmark and the way of using distortion analysis method to choose reference benchmark.It is proved that ground subsidence quantity is only a reference value and not the unique determining standard.We have proposed three demarcating standards and showed them with examples.
