多影响因子计算模型在城市地面沉降监测应用中的探讨--以菏泽市为例

摘要

In recent years, with urban development and utilization of underground water has been a large number of groundwater extraction, over time wil lead to surface subsidence. This paper describes changes in water table, pore water pressure changes and load changes on the ground surface subsidence ef ects of these factors impact mechanism;application of principles of regression analysis, the reference calculation model of land subsidence monitoring, with examples, analysis verified the accuracy of the model, for the next city to take the number and density of wel s to provide a scientific basis for laying.%近年来，随着城市地下热水被开发利用，大量地下水被抽取，久而久之将引起地表沉降。本文阐述地下水位变化、孔隙水压力变化和地面荷载变化对地面沉降的影响，分析这些因素的影响机理；应用回归分析原理，引用地面沉降监测计算模型，并结合实例，分析验证该模型的精度，为今后城市取水井的数量和密度布设提供科学依据。
