Treatmeat of the Sinking of the Reinforced Concrete Bridge

平顶山矿区铁路大部分位于矿区煤田之上 ,由于煤田的开采引起部分铁路随地表发生下沉。在对下沉的铁道线路进行整治中 ,出现问题最多和最难整治的是桥梁结构物。总结了矿区铁路田韩线DK56 + 6 6 5m处 3- 1 2 .0m钢筋混凝土桥梁多次发生下沉时 。

The majority of the mine railway in Pingdingshan lies on the coalfield of the diggings.For the sake of mining the coal,part of the railway showed the phenomena of sinking with the subsidence of the earth's surface.During the treatment of the sinking railway,we discovered that the bridge framework had got the most problems and was the most difficult problem to be treated.This article summarizes the treatment ways used for ensuring the unimpeded railway line on the bridge during the sinking appeared to the 3-12.0 m reinforced concrete bridge at DK56+665 m of Tian-han line for many times.
