【摘要】：隨著經(jīng)濟的發(fā)展和社會的進步,大型體育建筑作為經(jīng)濟文化的主要載體,承擔著越來越多的體育賽事、娛樂活動和集會事件,這些活動都伴隨著大量的人群聚集現(xiàn)象。20世紀以來,大型體育建筑內(nèi)的人群事故頻繁發(fā)生,高密集人群的安全問題引起了人們的高度重視,而體育建筑看臺區(qū)域是賽時大量觀眾聚集的主要區(qū)域,是人群聚集風險的高發(fā)地帶,而且一旦發(fā)生人群擁擠踩踏事故,后果極為嚴重,甚至伴隨著緊急疏散過程中次生災害的發(fā)生。已有研究表明,建筑空間環(huán)境和設施的安全設計對聚集人群在緊急情況下的心理和行為模式影響較大。但是,目前尚缺乏從人群行為這一視角進行建筑環(huán)境安全設計的系統(tǒng)研究。本文將群集風險理論引入到體育建筑看臺的人群安全設計。首先統(tǒng)計分析發(fā)生在大型體育建筑內(nèi)典型的人群事故案例,從宏觀上對事故的發(fā)生機理進行了梳理,包括事故發(fā)生的類型、特征、原因和發(fā)展階段分析;以事故的發(fā)展過程為脈絡,引入群集風險理論,旨在從微觀上探討聚集人群在正常和恐慌兩種情況下的心理和行為規(guī)律,重點探討建筑空間環(huán)境對人群心理和行為的影響;將這一理論應用在看臺區(qū)域,分析了看臺區(qū)域觀眾人群的構成、觀眾人群的觀看目的和動機,總結出看臺各重點區(qū)域可能出現(xiàn)的人群聚集風險。從整體上來說,看臺的安全設計綜合要素包括安全分區(qū)和安全容量、看臺功能、看臺分隔和疏散組織,并在看臺結構設計要素中,重點討論了看臺人群動態(tài)荷載的重要性。從局部來看,看臺瓶頸區(qū)域的人群滯留問題、群集狀態(tài)下看臺欄桿的安全設計以及看臺的視線設計、觀眾席設計、臨時看臺等細節(jié)問題也是看臺人群安全設計的重要內(nèi)容。緊急情況下的恐慌心理會導致人群的不適應行為,極易在建筑瓶頸區(qū)的疏散過程中出現(xiàn)拱形堵塞現(xiàn)象。這種現(xiàn)象是大量人群聚集場所需要關注的重點問題�；谌杭瘎恿W的理論方法,分析了疏散過程中拱形堵塞的形成機理及其影響因素;用人群密度、人群速度、人流通過率三個物理量構建出不同時段,在建筑瓶頸區(qū)的動態(tài)人群疏散模型,可計算出滯留人數(shù)和疏散時間;將STEPS軟件計算的結果與本模型進行了比較,證明了本模型的有效性;又通過一實例得出了建筑瓶頸區(qū)域的安全出口寬度的閾值。計算結果表明,當人群處于恐慌狀態(tài)時,出口的安全寬度和危險寬度之間僅一步之遙,細微的建筑環(huán)境的變化可以對人群行為產(chǎn)生巨大的影響。此滯留模型應用簡便,使用的參數(shù)易于獲取,可用來指導建筑的性能化設計,還適用于疏散路徑的選擇和優(yōu)化。對疏散安全出口的設置進行了探討,不均勻的出口位置會對疏散效率產(chǎn)生影響,具體闡述了解決這一問題的最優(yōu)化策略。通過調(diào)研國內(nèi)外關于欄桿設計的規(guī)范,比較分析了二者的不同,總結了我國與欄桿有關的規(guī)范要求的不足之處;從人群疏散的角度對欄桿進行了分類,針對不同的欄桿類型提出了相對應的研究重點;為了得出人群密度、人群傾斜角度和欄桿高度的定量關系,對已有的人群傾斜模型進行了修正,使之更加符合真實情況;通過實驗方法得出了人體能承受的安全壓力的大小,為欄桿的水平設計荷載值的選取提供了理論依據(jù)�？磁_的視線設計方面重點闡述了視線受阻可能引起的安全問題,論證了首排欄桿對視線的遮擋問題,并給出了優(yōu)化策略。在觀眾席設計方面對比了國內(nèi)外相關規(guī)范,提出了我國規(guī)范存在的一些問題。最后,基于以上研究,對比國際建筑規(guī)范中有關體育建筑看臺的安全設計原則,整合研究成果,對于看臺的分區(qū)、安全容量、觀眾座席區(qū)域、最短疏散距離、通道出口寬度等方面給出了切實可行的增補建議;從各類欄桿的位置、高度、水平設計荷載、構造要求等方面給出了規(guī)范建議,為完善我國體育建筑的相關規(guī)范打下了理論基礎。
[Abstract]:With the development of economy and social progress, the large sports buildings as the main carrier of economy and culture, plays a more and more sports, entertainment and rally events, these activities are accompanied by a large crowd gathered phenomenon in the.20 century, large sports buildings in the crowd accidents occur frequently, the security problem caused by the high crowded the attention of the people, and stand area sports building is a major regional tournament gathered a large audience, a crowd of high risk areas, and in the event of a crowd stampede, extremely serious consequences, even with the emergency evacuation of secondary disasters occur in the process. Studies have shown that the design of architectural space and environment safety the facility has great influence on the psychology and behavior mode in case of an emergency gathering crowd. However, there is still a lack of from the visual angle of crowd behavior The system of building environment safety design. In this paper the cluster risk theory is introduced into the design of sports building stands crowd safety. Firstly, statistical analysis of typical accident cases occurred in the crowd in the major sports in the building, from the macro mechanism of the accident are summarized, including the type, the accident characteristics, analysis of the causes and development stage; in the context of the development process of the accident, the cluster risk theory, aims to explore the psychology and behavior of the panic in normal and two cases gathered from the micro level, focusing on building space environment impact on people's psychology and behavior; this theory is applied in the stand area, analysis of the composition of the stand area audience the audience, viewing the purpose and motivation, summed up the key regional stands may appear in the crowd risk. On the whole, the safety design of the stands Combined elements include security partition and security capacity, stand function, stand separation and evacuation, and stand structure design elements, focuses on the importance of the crowd dynamic load. From the local perspective, the regional population bottleneck stands retention problem, cluster state stands railings safety design and the design of the audience stand the sight. Design, temporary stands and other details are important contents of crowd safety design. Maladaptive behavior psychological panic in emergency situations will lead to population, arch plug phenomenon easily in the construction area of the bottleneck in the process of evacuation. This phenomenon is a key problem for a large number of people gathering places in need of attention. Theory and method of cluster based on dynamics and analyzes the mechanism and influence factors of arch clogging formation in the process of evacuation; with the population density, population rate, rate of flow through the three physical quantities Built in different periods, people in the building dynamic model of evacuation bottleneck area, can calculate the number of remaining and the evacuation time; STEPS software calculation results with the model were compared to show the validity of the model by an example; and the construction bottleneck area exit width threshold. The calculation results show that when the crowd, in a state of panic, the width and the width between the security risk of the export of only one step away, subtle changes in the environment can have a great effect on the crowd behavior. This model of detention is simple in application, using the parameters can be easily obtained, can be used to guide the construction of the performance design, is also suitable for selection and optimization the evacuation path of evacuation safety. Exports were discussed, the uneven export position will affect the evacuation efficiency, expounds the optimal strategy to solve this problem. The research on standard railing design at home and abroad, compares the difference between the two, summed up the inadequacies of standard of our country and rail related requirements; the classification of rail from the evacuation point, according to the different types of bars and puts forward the research emphases correspondingly; in order to get the quantitative relationship between population density, population the tilt angle and the height of the railing, the existing population tilt model was modified to make it more in line with the real situation; through the experiment method that the safety pressure of the human body can withstand the size of bars level design load value provides a theoretical basis for the selection of the line of sight. Stand design focuses on the blocked security issues may be caused by the occlusion problem demonstrates the first row of the railing on the line of sight, and gives the optimization strategy. In the audience design compared the relevant norms at home and abroad, put forward Some problems existing in our specification. Finally, based on the above research, the safety design principle about sports building stands compared with the international building codes, the integration of research results, for the stands of the partition, security capacity, the audience seating area, the shortest evacuation distance, exit width etc. gives practical suggestions from the height of supplement; all kinds of rail position, the level of design load and structural requirements are proposed to improve the relevant norms, norms of China's sports architecture has laid a theoretical basis.
