摘　　要：本文以某学院6号楼为例,研究标识设置对教学楼通道疏散能力影响,测定了不同标识设置情况楼道人流时程,结果表明:自然状态人流速峰值66.8人/min,持时2.823 min,拥堵明显;立体标识使人流速峰值提升3%,使峰值持时缩短51.65%,墙面平铺张贴标识使人流速峰值提升1%,使持时缩短44.07%,立体标识优于墙面平铺张贴标识;早期疏导标识使人流速峰值提升6%,使持时缩短60.93%,使峰值出现时刻比自然状态提前约31%,疏散效果明显。同时本文分析了现有标识设置的问题和弊端。The paper uses one teaching building as an example, researches the impact of public guiding signs on the evacuation in teaching buildings. The results show： in the natural state, the pedestrian flow was 66.8 persons per minute, lasting 2. 823 minutes; three-dimensional guiding signs increase the flow by 3% , reducing the time by 51.65% ; guiding posters increase the flow by 1% , reducing the time by 44.07%. Early guiding signs increase the flow by 6% , reduce the time by 60. 93% , and make the peak moment 31% earlier than usual, showing an obvious effect. The paper also analyzed the existing problems of the public guiding signs.
