【摘要】 体育场内场风环境是建筑设计者和体育工作者非常重视和关心的问题。因为它涉及到运动成绩被承认与否和体育比赛的效果。本文针对浙江省黄龙体育中心主体育场的建筑结构特点，对其内场近地面的风场进行了测量，并采用空气动力学实验中经常使用的热线风速仪和烟线示踪法对各种不同风向角条件下，外场风在现体育场结构方案中对场内带来的影响，显示内场风场的变化。对体育场建成后的使用，提出风影响预报。可以避免今后由于风作用而产生不利影响时的盲目性。同时可以采取一些相应的补救措施，更能提高体育场的使用性能。更多还原

【Abstract】 The wind field inside an athletic ground is always very much concerned both by architects and sporting world since the wind field influences the sports results and the effectiveness of records.Described in the present paper are measurements of the near ground wind field inside an athletic ground model obtained in atmospheric boundary layer wind tunnel experiments.Various aerodynamic means such as hotwire anenometer…,smoke trace visualization technique and so on,were used to investigate the wind field variations inside the athletic ground under different wind conditions (direction and velocities) outside the ground.Predictions were made of the wind influence for the athletic ground when it is actually utilized.Such experimental study may greatly reduce the potential risk of the intolerable wind effects on the sporting activities and meantime some remedies can also be recommended through such aerodynamic studies.更多还原
