松卜岭隧道采空区治理

松卜岭隧道穿越大量采空区，采空区的存在使得隧道施工面临很大的安全问题，人员与机械设备都可能掉入采空区内部受到伤害，故应先治理采空区，然后再进行隧道施工。对此特提出采空区的处理方案。根据实际情况出发，采用从地面治理和洞内治理两个方面进行处理。通过检测，证明此方案是行之有效的。

Management of Worked out Section along Songbuling Channel

Songbuling Channel passes through various worked out sections and the existence of such sections brings serious safety problems to the construction of the channel. Workers and the facilities may fall down to the section holes and get injured or broken badly. So worked out sections must be dealt with before the construction of the channel. Therefore, the treatment scheme of the worked out section is hereby provided. According to the site condition, two treatments, on -the -ground treatment and inside -the -hole treatment, shall be done together. It is proved that this treatment scheme is the most efficient in solving the problem.
