| Abstract: | Owing to the landslide and unsteady slop because of the railway cut, the section of Shihe tunnel beneath the railway is very difficult to construct. In this engineering field, the long tubular shanty grout injection and some new relevant techniques are adopted. It proves that it is effective to reduce the vibration and strengthening surrounding rock. |
