粉喷桩与土工格栅联合加固及其工程应用

Reinforcement of DJM Combined with Geogrid and the Engineering Application

摘要:

桥坡段结构物处为防止结构物开裂、位移、基桩受剪破坏及控制工后沉降,采用粉喷桩与土工格栅联合加固软基。联合加固后，可约束地基侧向变形，减小路基挤出量及不均匀沉降，有效地减小了地表的总沉降量，对于预防桥头跳车有良好的效果。

Abstract:

To prevent the bridgehead segment structure cracking, displacement, shear failure and the pile settlement after construction, DJM and geogrid joint reinforcement is used in soft ground reinforcement. It can bind the lateral deformation of the foundation; reduce the differential settlement of embankment and roadbed extrusion, effectively reduce the total settlement amount of the surface with good effect for preventing vehicle bouncing at bridge approach.
