河源洞浅埋偏压小净距隧道进洞施工技术

Entering cave construction technology of the Heyuan tunnel with shallow buried and bias pressure small clear spacing

通过河源洞隧道实例,对小净距浅埋偏压隧道洞外加固措施、进洞顺序选择、施工工序安排、监控量测等关键的技术措施进行了探讨和总结,从而为类似隧道的施工积累经验。

According to the Heyuan tunnel case,it discusses and concludes several key technology measures of the small clear spacing bias pressure and shallow buried tunnel,such as reinforcement measures out the cave,entering cave procedures selection,construction procedures arrangement and supervision measurement,thus accumulating experiences for similar tunnel construction.
