地下水对南水北调中线西四环暗涵工程设计的影响分析

南水北调中线西四环暗涵工程区地下水问题的分析评价关系到工程设计方案的比选、设防水位的确定及施工安全的保障等.通过对工程区水文地质条件的勘察分析,基于对其补、径、排的动态变化规律的认识,为设计方案比选、设防水位的确定及施工安全影响提供合理可靠的依据与建议,以期实现设计方案合理、施工安全的目标.

Analysis on effect of groundwater on design of buried culvert under West No. 4 Ring Road in Beijing for Mid-route of South-to-North Water Transfer Project

The analysis and evaluation on the problems from the groundwater within the construction area of the buried culvert under West No. 4 Ring Road in Beijing for the Mid-mute of the South-to-North Water Transfer Project are related to the comparison on the design scheme, the determination of the defence water level and the guarantee of the construction safety. Through the analysis on the hydrogeolngical condition of the construction area, the reasonable and reliable bases and suggestions are provided for the comparison and determination of the design schemes based on the understanding of the law of dynamic changes from the water-recharge, water-drainage and runoff, so as to realize the objective of reasonable design scheme and safe construction.
