The research of flexible gabion in highway engineering 

In recent years, flexible gabion structure has certain application in water conservancy, road engineering, flexible gabion is a flexible retaining protective structure, compared with the rigidretaining protective structure, has more extensive adaptability characteristics. I section in highwayengineering practice tried flexible gabion structure used and using effect of flexible gabion structureaccording to, that is worth to promote the use of Engineering structure.

I try to use several section of flexible gabion structure or combination form:
(1) flexible gabion retaining wall foundation of slurry wall body.
(2)  flexible gabion based mortar (dry masonry) tablets (block) stone revetment.
(3) the stone cage based semi rigid flexible gabion retaining wall.
(4)  flexible gabion foundation of flexible gabion retaining wall (Hu Po) etc..
Application of 2 flexible Gabion
Application of 2.1 flexible gabion in water damage restoration of
(1) no drainage of flexible gabion foundation in 1995 Gao Bao yellow line ditch bridge destroyed roads damaged when the survey found that the washout of flood period is Lukido after flash floods,water erosion to concentration, although the flood rapidly, but the waters receded, often scour pitand surface water damaged roadbed or protective, although the surface water is not deep, but thebed slope is large, underground water and the flow velocity is larger, restore the roadbed orprotective engineering usually takes the drainage construction, drainage fees - like protection engineering cost accounts for larger proportion, and the construction quality of masonry foundation is not easy card. For the restoration of subgrade protection project as soon as possible, to reduce the cost of protective engineering, my first attempt to use the "no drainage section of flexible gabionfoundations" mortar walling body combined structure, namely flexible gabion mortar rubble stonefoundation. The basic characteristics of flexible gabion is foundation construction without drainage,can use simple cofferdam diversion to reduce surface water, foundation excavation reaches the design depth, can be laid rectangular stone cage net (box), packing sheet (block) represent the water 0.2m, backfill foundation after the mortar rubble retaining wall construction, generally nodrainage of flexible gabion foundations work with water construction depth is less than 1.0m, so the flexible gabion foundations for shallow foundation protection engineering.
