| Abstract: | This paper focuses on the rail transit of DK32 + 300 to DK32 + 927.303 in GZH-5 contract section between Dongguan and Huizhou to study the ground settlement and stress of the support structure of the shallow excavated tunnel in weak water-rich layer and the influence of advanced grouting on the settlement and stress by means of model tests in two groups:one with advance grouting,the other without.Finally,some construction suggestions are put forward for the shallow excavated tunnel in weak water-rich layer. |
