前言 1987年8月由浙江省交通设计院委托我院承担宁波甬江水底隧道通风设计,通过一年努力,已于1988年3月和7月相继完成通风扩初设计和施工图设计。预计该隧道1990年底可开通。现就甬江水底隧道概况、通风量计算、通风方式选择、通风机技术参数、通风机房布置和通风系统以及环境预测评价等等作一介绍,供同行们参考。 Foreword In August 1987, commissioned by Zhejiang Traffic Design Institute, our college undertook the ventilation design of the Ningbo Yongjiang underwater tunnel. After one year of hard work, it completed the design and construction drawings of ventilation expansion in March and July 1988. The tunnel is expected to be opened by the end of 1990. Now the overview of the Yongjiang water tunnel, ventilation calculation, selection of ventilation, ventilation fan technical parameters, ventilation room layout and ventilation systems and environmental prediction and so on to introduce an introduction for your colleagues.
