Research On Humanized Design Optimization Of Subway Entrance And Exit Space From The Perspective Of Resilience

With the rapid development of urban infrastructure in China,many large cities have begun the construction of subway systems to solve problems such as urban traffic congestion.As the evacuation space of the subway system,the subway entrance and exit space is an important link between the subway interior space and the urban ground space,and should have enough safety,comfort and toughness.However,looking at the construction status of subway entrance and exit space in recent years,there are some problems such as poor safety,poor identification,inconvenient transfer and other humanized design toughness,which bring great inconvenience and trouble to subway passengers and citizens.Therefore,from the perspective of toughness,through theoretical research,case study and questionnaire survey,this study selects and determines the toughness elements of humanized design of Qingdao subway entrance and exit space.On this basis,through questionnaire survey,field investigation,graphic quantitative analysis and other methods,the paper analyzes and summarizes the existing problems of humanized design toughness in Qingdao Metro entrance and exit space,and tries to propose targeted optimization strategies for humanized design toughness.The main contents of this study are as follows:First,consolidate the theoretical research foundation of the study.Under the background of the present situation,the origin,purpose and significance of studying the humanized design toughness of Qingdao Metro entrance and exit space are clearly discussed.This paper analyzes the current research status of toughness theory and humanized design of subway entrance and exit space,and summarizes the shortcomings and problems in the current research.At the same time,the relevant theories and concepts of the study are expounded,and through the analysis of typical subway entrance and exit space cases at home and abroad,the inspiration of the optimization of the humanized design toughness of subway entrance and exit space is obtained.Secondly,it constructs the framework of toughness elements of humanized design of Qingdao Metro entrance and exit space.On the basis of the existing research and theory,combined with the crowd behavior analysis and design principles,summed up the initial elements of space humanization design index.Then through the selection of local experts and teachers in Qingdao,focus group interviews,importance triangle fuzzy number optimization to screen and verify,get the final Qingdao metro entrance and exit space humanized design elements index.Based on the theory of toughness,this paper integrates and optimizes the factor index,extracts the toughness factor,and finally forms the framework of toughness factor in humanized design of Qingdao Metro entrance and exit space.Thirdly,the paper studies the humanized design toughness of Qingdao Metro entrance and exit space.On the basis of the framework of humanized design toughness elements above,a sampling questionnaire survey and field investigation were conducted on the entrances and exits of Qingdao Metro from four parts: the building space of the entrance,the rest and distribution space,the traffic transfer space and the green landscape,and the survey results were illustrated and quantified,and the main problems of humanized design toughness in the entrances and exits of Qingdao Metro were summarized.Finally,a specific optimization strategy is proposed and verified by an example.Based on the previous theoretical case studies and problem investigation and analysis,targeted optimization strategies are proposed from the dimensions of safety resilience,traffic resilience,environmental resilience,barrier-free resilience,short-term rest resilience,regional culture resilience and image art resilience.Then,taking Qingjiang Road station of Qingdao Metro Line 3 as the application object,the toughness optimization design of the humanized design of the entrance and exit space is carried out to verify the feasibility of the optimization strategy.This study innovated the theory of toughness into the micro-perspective of humanized design,and studied the optimization strategy of humanized design toughness level of Qingdao subway entrance and exit space from the perspective of toughness.This not only enrichis the connotation of toughness theory and humanized design theory,but also provides a certain theoretical basis and practical reference for the future construction of urban subway entrance and exit space.
