| Abstract: | The geological characteristics of the lime rock stratum of the Guangzhou Subway is introduced in the paper,which points out that when a shield is used for construction in lime rock stratum,karst and earth holes have to be pre-treated.The causes of gush,the shifting of the shield and the up-moving of the gilled tubes occurring during the drilling operation are analyzed,with control measures put forward.It may serve as a useful reference for other similar projects. |

| Keywords: | shield lime rock stratum pre-treatment of karst and earth holes gush at the screw conveyer jamming of the shield |
