| Abstract: | Several rock fallings have taken place along the Zhongxian-Wuhan gas pipeline since it was put in operation in the end of the year 2004.Falling rocks destroyed the pipeline protection cover and injured the pipeline,thus seriously imperiling the pipeline operation.The characteristics of Shimaling unstable rock masses have been described,and focuses are put on the discussion and determination of the designs for the control of the unstable rock masses.Two design schemes,unstable rock masses cutting + bolting and pipeline covering,have been compared with respect to their advantages and defects.The scheme of unstable rock masses cutting + bolting is believed to be more suitable for the local conditions and the aim of pipeline protection. |
