摘 要：Abstract：The invention relates to an anti-slide tie-steel pipe pile composite structure for repairing a cave-in roadbed and a method, which belong to the technical field of constructional engineering. The anti-slide tie-steel pipe pile composite structure for repairing the cave-in roadbed comprises prefabricated anti-slide ties, a prefabricated steel pipe pile and inhaul cables, wherein the prefabricated anti-slide tie is fixed in a stable soil under a cave-in body; the prefabricated steel pipe pile is arranged at the front edge of the cave-in body and fixed in the stable soil body; the inhaul cable is flatly laid in a fill; and two ends of the inhaul cable are respectively fixed on the prefabricated anti-slide tie and the prefabricated steel pipe pile. The anti-slide tie-steel pipe pile composite structure further comprises geogrids, wherein the geogrids and the inhaul cable are simultaneously laid in the fill; and the two ends of the geogrids are respectively fixed on the prefabricated anti-slide tie and the prefabricated steel pipe pile. The invention further provides a method for repairing the cave-in roadbed by using the anti-slide tie-steel pipe pile composite structure. The whole repairing method is simple in the construction process, the road repairing time is saved, and the method is suitable for roadbed cave-in projects which need to be rapidly repaired. The anti-slide tie-steel pipe pile composite structure for repairing the cave-in roadbed exerts a very good anti-slide supporting and retaining effect and can also preferably reduce roadbed settlement due to being provided with the geogrids.
