Based On The DHGF Integration Methods To Optimize The Planning And Designing Of The Mountainous City Utility Tunnel Research

With the rapid development in urbanization of our country,very often,the roads zipper phenomenons and pipe systems accidents are resulted from the frequent expansion,replacement,and repairing of the municipal pipe system.Building the utility tunnel,can be a good solution to the problems.At the same time,it is also an effective way to remove the density air wires system,modify the look of the city,relieve the urban water logging,ensure the safe and smooth operation of whole city.With the rising tide of building utility tunnel,taking the close relation between the utility tunnel and the geographic conditions into consideration,in the mountainous city it is very necessary to specially research the planning and design of the utility tunnel,enhance the level design and planning of the utility tunnel,and optimize planning and design.This essay,selecting mountainous city Chongqing as its studying area,regarding the mountainous geographical features,systematically researched the mountainous city utility tunnel planning,engineering project designing,and affiliated facilities.The main content are the following: the construction of the mountainous city utility tunnel,system arrangement,the pipe &wire in the utility tunnel,the compatibility among the pipes and wires,the volume requirement of wires and pipes,standard section design,space design,vertical design,knot design,the design of the affiliated facility and so on.One of the findings from the research was that the main influential factors of the planning and designing of the mountainous city utility tunnel are: construction location,system arrangement,wires and pipes in the tunnel,and standard section.Regarding the the current studying state of the judge and the selection of the in-tunnel wire and pipes,and the complicity of the selection of the in-tunnel pipes and wires,in this essay,the improved DHGF integration methods,has been adopted to set up an universal selecting & judging index system for the in-tunnel wires and pipes in mountainous city,put out an selecting and judging theory on in-tunnel pipes & wires,Besides,DHGF integration methods is applied to the engineering practice of selecting and judging the in-tunnel pipes and wires in the mountainous city.And we get a result which is the same as the actual decision expectation.So the effectiveness and dependability,the practicability of the DHGF integration methods,for selecting & judging the in-tunnel pipes and wires in mountainous city have been tested and proven.Applying DHGF integration methods to select and judge the in-tunnel pipes and wires in mountainous city,can make full use of the accuracy of Math computing,the collective experience and designing advantages of the utility tunnel designing experts,enhance the rationality and the accuracy of the the selecting and judging of the in-tunnel pipes &wires in the mountainous city,provide an effective way of planning and designing the utility tunnel,in mountainous city,having a rather good significance in theory and practice.
