北京市城近郊区工程排水对地质环境和建筑物影响分析

近些年来， 北京市城近郊区工程排水工程日益增多， 工程排水会产生以下不良后果： （１） 浪费水资源； （２） 导致地面沉降和对周围的高大建筑物稳定性产生影响； （３） 使周围地区地下水水位局部下降，形成小范围的水位降落漏斗， 导致地下水水质下降。因此， 有必要进行这方面的调查和研究工作

THE ANALYSIS OF EFFECT ON ENGINEERING DRAINAGE FOR GEOLOGICAL ENVIRONMENT AND BUILDINGS IN THE SUBURBS IN BEIJING

In recent years,the engineering drainage in suburbs in Beijing become more and more.The engineering drainage have some unhealthy effects,such as (1)wasting water resource (2)bring about the land subsidence and influencing the stability of high buildings nearby (3)to make the groundwater level drowdown in some area to cause the cone of groundwater level depression in small area and bring about the groundwater quality depression,so that,it is necessary to investigate and research in this field.In this paper gives a detailed analysis and propose some feasible suggestions.
