Abstract The shield running tunnel of the Guangzhou-Foshan rail transit project passes through many anchor ca? bles of an adjacent foundation pit. The advantages and disadvantages of the common treatment schemes for this problem are analyzed in terms of the construction period, construction cost, etc., and a construction scheme combining ground rotary drilling and cutting with shield driving is proposed based on reasonable driving parameters, which eliminate the anchor cable effect on the shield construction and avoid the influence of large-area excavation on the surrounding environment.
