Study On Aesthetic Design And Evaluation Of Highway Tunnel Portal

People's material standard of living has improved steadily,and the requirements for things have been transferred from a purely functional point of view to environmental protection,comfort and beauty.As for the tunnel engineering,because of its own characteristics of the restrictions(hidden,not intuitive,etc.).With the increase of the number of tunnels,its aesthetic problems will gradually enter into people's vision,This is a need to design guidance and scientific evaluation system.In this context,the tunnel entrance as a breakthrough,The integration of aesthetics,tunnel engineering,landscape design and regional culture determines the status of aesthetic design in the design of Tunnel Engineering.And from the hole structure and landscape design were analyzed.Through the establishment of a scientific evaluation index system.This paper uses the analytic hierarchy process(AHP)and fuzzy comprehensive evaluation method to determine the aesthetic evaluation method of the highway tunnel entrance,and put forward a practical stage evaluation method.Then,using the concept of human,vehicle,system environment,simulation driving experiment based on virtual reality,conducts the research to the highway tunnel portal aesthetic evaluation,analysis of sensitivity analysis of the aesthetic factors using multiple factors.The conclusions are as follows:1.The project can be reflected in the function of beauty,beautiful environment,natural beauty,form beauty and cultural beauty in five aspects.These five aspects are mutually restricted,but they promote each other.2.In the long run,the enjoyment of the spirit,the pursuit of aesthetic in the proportion of human life will be greater and greater.The aesthetic of highway tunnel should be considered at the same time from two levels of static perception and dynamic feeling.3.Our country puts forward 11 design of tunnel portal of regional culture and road links,the status of regional culture in highway tunnel portal design: culture should also be out of function;culture and security are not contradictory;avoid the "zero" cultural design;may not be superior to the natural environment on cultural design.4.The methodology of Aesthetic Research on highway tunnel portal.Evaluation of the answer,meaning world and value world life experience the nature of the problem,the problems of the human psychology description or experiment can not be solved,only by philosophy,so the evaluation should combine qualitative and quantitative analysis;the design should be "appropriate Tour" and "Le Tour" in two levels,design aesthetics is the effective way to achieve "Le Tour".5.At the same time,considering the construction scheme of tunnel,the design of the tunnel will be integrated into the overall design of the tunnel.Aesthetic design into the design of the structure,to solve this problem the most important thing is to form a technological innovation as the main mode of thinking,at the same time,the results of technological innovation must reflect the aesthetic of promotion,to form a "unity of technology and beauty" win-win.6.The landscape design is divided into several levels,that is,"point" elements,"surface" elements,"line" elements."Point" refers to the elements of the design of the portal,"face" refers to the design elements of the surrounding environment,the "line" refers to the elements of style design across the board;and the "point" and "surface" elements may cross substitution(i.e.core landscape conversion).With the help of these three levels,the "landscape" of highway tunnel entrance is expressed by means of unity,harmony,contrast,symmetry,balance,proportion,rhythm,repetition,gradual formation and contact separation.7.Through the scientific selection of aesthetic evaluation indicators,the establishment of a functional,environmental,aesthetic,economic evaluation of the four indicators of the overall system.Combined with system engineering and analytic hierarchy process,the evaluation method of highway tunnel entrance is presented.By using the method of fuzzy comprehensive evaluation,a simple quantitative method is given.8.From the point of view of human,vehicle,environment three,using virtual reality technology to carry out the driving simulation test,through the test of people's feelings,impact factor analysis evaluation of highway tunnel aesthetic law carries out sensitivity analysis of multiple factors.
