摘要
沿海三角洲城市地面沉降地质灾害十分频繁,根据多期离散观测值进行城市地面沉降分析和预测对地质灾害防控非常重要。本文对基于多期离散沉降观测数据的城市地面沉降预测模型进行了系统分析与适应性评价,以温黄平原地面沉降预测为例,对双曲线法、三点法、Asaoka法和灰色理论等四种典型城市地面沉降预测模型的精度和适用性进行分析评价,为城市地面沉降预测模型选择和沉降监测防控提供依据。
The geological disasters of ground settlement are very frequent in the coastal cities,so it is very important to forecast geological disasters based on observed multi-epoch discrete data by analysis and prediction of urban ground settlement.This paper systematically analyzes several models of prediction of urban ground settlement,and evaluates their adaptability.In the case of the observed data of Wen Huang plain,detailed analysis and evaluation of the precision and the adaptability of four typical forecast models for urban ground settlement is done,such as double curve method,three-point method,Asaoka＇s method and grey theory.This paper provides the basis for the choice of the forecast models,the monitoring and the prevention of ground settlement.
