摘　　要：目前国内公路隧道竖井的设计和施工方面尚无较成熟的经验,仍需作进一步的研究与探讨。结合在建的南—大—梁高速公路华蓥山特长公路隧道通风竖井的设计及施工方案,阐述当前较为成熟的深竖井围岩压力秦氏计算理论,介绍采用的竖井围岩压力的计算方法,探讨公路隧道竖井施工方法的特点及适用条件,并对公路行业竖井设计与施工的规范与规程的迫切需要、秦氏竖井地压计算理论的参数取值问题及反井钻机设备的亟待研发等提出几点建议。There is no successful experience in the design and construction of ventilation shafts of long highway tunnels in China. The calculation theory for the rock mass pressure of deep shafts is presented, with the ventilation shafts of Huayingshan extra-long highway tunnel as examples. The characteristics and application conditions of different shaft sinking methods are discussed. Advices are made on the necessity of code for design and construction of ventilation shafts of highway tunnels, the parameter selection in the rock mass pressure calculation and the development of raiseboring machinery.
