| 英文摘要 | Typical large-deformation phenomena of soft rock occurred frequently during tunneling in Huangjiazhai Tunnel. The monitoring results indicated that the deformation had the characteristics of large magnitude, high velocity, long duration and inhomogeneity of spatial distribution. The results of in-situ stress test showed that, as a result of high tectonic stress and lower rock strength, the drilling test area of tunnel was regarded as extremely-high stress area, even if the maximum buried depth (270 m) of tunnel was not too large. Based on the New Austrian Tunneling Method, new comprehensive supporting measures were utilized in Huangjiazhai Tunnel, which were consisted of increase of the reserved deformation, bolt and grouting supporting, accelerating the construction of inverted arch and secondary lining and adjusting the spacing and type of steel arch. It was proved in the subsequent construction that the above supporting design was effective for controlling the large deformation in Huangjiazhai Tunnel. |
