Study On Sport Venues Design From The Perspective Of Public Security

Security is one of the four elements of the global strategy for sustainable development.Due to natural and man-made disasters often occur in21st century, public safety issues havebeen referred to an unprecedented height. As sport venues is the highly-crowded urban publicplaces, the sudden public safety events will caused huge casualties, economic damage andserious negative social impact. As construction of sport venues and sports undertakingsdeveloped vigorously in China, the research of sport venues about security issues is a strongstrategic and forward-looking study.In order to protect people against harms, Based on the own characteristics of sportvenues, this paper carried out applied research for sport venues to defense the sudden publicsafety events such as crowded evacuation, fire disaster, explosive attack, biochemical attackand violence in arena. The first two disasters are the core design problems for sport venues.The evacuation design specification and weaknesses was analyzed in this paper, thecorresponding fire protection design strategy was proposed for the different stages of the fire,the anti-fire method of the performance-based pattern was affirmed certainly in large spacebuildings. The concept of stadium violence was proposed and analyzed in this paper. Threekinds of venues isolation safety design measures such as protective fence protective ditch andprotective wall were proposed in this paper. Anti-Terrorism disasters are the design hotproblems for sport venues. The explosion-proof strategy was discussed from three aspects ofestablishing the border, strengthening the anti-explosion and detecting early. The idealanti-explosion pattern of gymnasium was proposed in this paper also. Generalanti-biochemical response method is summarized; anti-biochemical design strategies werediscussed from the aspects of source control and air distribution. The causes of violence inarena were analyzed, and the design method of isolation between stand and the field of playis proposed in this paper.The potential advantages of sport venues for sheltering was analyzed fully from outdoorspace and main building, the domestic application status was introduced and the foreignadvanced experience was summed up in this paper. This paper also proposed the designstrategies and methods for sheltering which integrated and converted for normal time anddisaster time after deep think on the sheltering capability of sport venues. It put forward threeplan strategies based on the outdoor environment which were introducing the concept of disaster prevention unit, preparing emergency facilities, landscape element’s adaptation toshelter, and three design strategies based on the main building which were natural light andnatural ventilation, improving the rate of using indoor space, all-purpose use of auxiliaries.The study took Guangzhou Nansha sports center as a case for practice, reformed the existinggymnasium, and implanted the function of sheltering on the second stage in advance. Finallysports center becomes long-term accommodation type shelter which services Nansha Districtmainly and extends to the surrounding cities.Study set up a mathematical model to evaluate the security of sports venues by using theFuzzy Analytic Hierarchy method based on the risk theory. Author selected the Top4high-risk public security incidences by risk analysis which include crowded evacuation, firedisaster, explosive attack and violence happened in sport evenues, then determined theevaluation indexes and their weight rank by using Analytic Hierarchy Process method, andtranslated the subjective evaluation of professional persons into quantitative results by FuzzySynthetic Evaluation method. This paper carried out the safety assessment research based onarchitecture design and use management by taking Guangdong Olympic Stadium as a casestudy.Large security concept" which based on important sports events was proposed from thelevels of climate safety, social security, city lifeline and food safety. The key points ofsecurity plan were analyzed in-depth from six aspects of accessibility, passageway,territoriality, entering-control, barrier-free design and risk management during the game-time.Research proposed an assessment methodology for the security of sport venues based on thetheory of crime prevent through environment design, by which set up an assessment structurefrom three categories of manage and policing, monitoring and design, access and territoriality,and created10game-time controlling indications and10game-time public indicationsseparately. Then it took Tianhe stadium that hold final football match of16th Asian games asa study case to test this assessment methodology.
