Comprehensive Evaluation Of Groundwater Control On The Surrounding Environment Influence And The Countermeasures Research

At present,the scale of urban underground space development and utilization in China becomes even larger,and the underground engineering projects increases a lot.With the increasing depth of underground space development,the construction becomes more difficult than before and the main restrictive factor is groundwater.On the one hand,groundwater affects the construction safety,quality and progress of underground engineering projects,on the other hand,it also influences the surrounding environment.Currently the main approaches to control groundwater are construction precipitation and water plugging during the construction process.However,these two methods inevitably affect the surrounding environment in some way.From the plenty of examples for groundwater control construction,we can see that some has little influence on the surrounding environment,while the other can bring huge affects even cost people’s life and property.So to evaluate the influence of groundwater control construction for surrounding environment before the projects begins,and to work out reasonable measures to decrease the influence to its minimum means a lot.In the thesis,the author provides plenty of construction examples,concludes and classifies the different influences.The anthor puts forward a conclusiion that we can use analytic hierarchy process to make a synthetical evaluation according to its various influence in different environment,and to choose the method which affects less on the surrounding environment.Furthermore,we can use various calculation models to give those influencing factors different weight value to have a quantitative forecast.In the end,the author puts forward some solutions to control the influence...
