摘　　要：以官田隧道施工通风为研究对象,结合数值模拟和现场实测,对井筒效应进行深入分析,并对近交叉通道和井筒底部的风机布置进行了优化。结果表明,风机在轴与排气连接通道之间距轴5 m处安装是合理的。射流风机布置的最佳区域在气流方向下,靠近十字通道且不宜距十字通道太远,最好安装在较高的位置。Based on the air ventilation in construction of Guantian tunnel,this paper adopted numerical simulation and field measurement to carry out in-depth analysis on shaft effect and to optimize the arrangement of air fans near cross passage and shaft bottom.It was found that it is reasonable to install the air fan between the axis and air ventilation channel and 5m to the axis.The optimal installation position for jet fan is below the air flow and near the cross passage,and it should be better installed at a high position.
