Design of Deep Foundation Pit Dewatering and Analysis on the Influence of Dewatering on Surrounding Environment

In order to solve the problem of foundation pit dewatering,this paper explains the main functions of dewatering and discusses the common method of precipitation.Taking a deep foundation pit dewatering engineering as an example and in combination with the engineering geological and hydrogeological conditions,the paper selects a reasonable precipitation scheme to carry on the dewatering design on the basis of the explicit key points of the dewatering design,discusses the influence of deep foundation pit dewatering on the surrounding environment and discusses the corresponding treatment measures.Furthermore,opinions and suggestions for common problems of deep foundation pit dewatering engineering are put forward.
