Eco-Bag Retaining Wall

Retaining wall of geotextile block is construct by way of unit heap method, its stability same as gravity type wall is depend on self weight.
It take two parts to discuss its stability;
1. External stability
2. Internal stability.
Most of geotextile block wall are direct connection by plastic plate and not use chemical mortar, only can provide about 200-400 lb shear resistance, it is unsafe for structural stability. For general of soil or rock slope always landslide from rainfall \efflorescence\weathering or earthquake, traditional method only can protect the slope not sliding from erosion or weathering. You can take intalok long block method, package thickness of soil can be up to 22-30 cm, also connection by plastic plate and use chemical mortar then combined by anchor, so can protect the slope from sliding and supply enough water/nutrient for plant growing up need.

Ground work nonwoven geotextile bag because of it is gentle again have variety function, past drive extensive usage in the earth engineering, but with ground the ecosystem bag make into by work fabric, it can usage in it the scope is equal extensive. Such as the ecosystem bag usage is on the side ascent, in addition to can reduce the ascent noodles it flush erosion, in stuff with grass kind in the ecosystem bag and fertilizer, can at not easy plant to living of the side ascent top provide the environment of[with] the plant growth. If used for the river shore to protect an ascent, the ability flush and the balance of the maintenance ecosystem chain Be the highway embankment and combine to add the material can be a great deal of to cut to accumulate with the ground, and attain the highway ecosystem to beautify of result. The purpose of this thesis at the study be engaged in the ecosystem bag to block the soil wall structure analysis should attention of important point and long the bag anchor man solid method application in the side ascent stability its characteristic.
Because the ecosystem bag block the soil wall pattern and piece type to block the soil wall likeness, all the heap is construct by the way of the, so general of the ecosystem bag block the soil wall can concrete in the reference the United States carve the body association(the National Concrete Masonry Association, NCMA) provide of the piece type block the soil wall design manual(the Design Manual for Segmental Retaining Walls) and local highway to add soil engineering design norm, the highway roadbed design norm, the water work to block the soil wall design norm, ground the work synthesize the material norm to carry on a stability analysis.

The ecosystem bag block the soil wall to fasten the way of the to construct from the heap, its stability and the gravity type block the soil wall a homology, is all provided a stability by the wall weight quantity. Main cent two part:

On is an exterior stability(the external stability), analysis the hour see to an all unit whole carry on analysis, break pattern, such as diagram, 1 show, include the level glide to break, dump to break, loading the dint break, this kind the safety of the type analysis, can according to the tradition of block the soil wall analysis way calculation. If the stability analysis result can't attain the safety standard, then can combine a ground of work mesh(geogrid), anchor man to nail or thicken a heap of way to come to its whole stability of increment.

Two is the inner part stability(the internal stability), such as diagram 2. At NCMA the design is in the manual consider shear dint break, this break fasten because of the piece it shear the dint strength shortage cause it break.
