Bidirectional pulling construction method for filling and excavation junction area of inclined excavation step type roadbed

The invention discloses an inclined excavation step type roadbed filling and excavation junction area bidirectional pulling construction method, which is characterized in that inclined steps are arranged to provide a transverse and vertical lap joint operation platform, geogrids are arranged on the transverse and vertical lap joint operation platform, and the inclined geogrids enable the operation platform to provide stress in the transverse direction and the vertical direction; the capacity of resisting differential settlement damage is improved, and transverse, longitudinal and vertical pulling force is improved, so that the settlement amount of a roadbed at the filling and digging junction is reduced, the possibility of pavement subsidence, cracking and damage is reduced, and the service life of a road is prolonged. 本发明公开了一种斜挖台阶式路基填挖交界区双向拉结施工方法，通过设置倾斜台阶提供横竖搭接作业平台，在所述横竖搭接作业平台上设置土工格栅，倾斜的土工格栅使作业平台横向和竖向均可提供受力，达到提高抵抗不均匀沉降破坏的能力，并且提升了横向、纵向和竖向的拉结力，从而降低填挖交界处路基沉降量，减小路面沉陷、开裂、破损的可能性，延长道路使用寿命。
