The analysis of soil nail support technology under different geological conditions 1 The soil nail reinforcement in soft surrounding roadway For the soft surrounding rock of roadway maintenance,it has always been the most difficult to conquer links of engineering construction.Due to the soft surrounding rock deformation easily,reliable performance is poor, so it is not easy to maintain, cost is large, so the mine work will have a big impact on the safety, ordinary anchor bolt support has already could'nt solve the problem of the protection of the soft surrounding rock.For soft rock supporting require a higher technology maintenance way, anchor reinforcement. Anchor reinforcement is injection, the use of hollow anchor grout injection to them, lose in the surrounding rock, and thus to add easy loose or cracked surrounding rock Solid, thus improved the strength of the surrounding rock, to the stress of the roadway is also reduced, which can keep the surrounding rock stability of the state. 2 Anchor net and anchor rope combined support for composite caving roadway Composite roof support work is relatively complicated, because of its soft base, the binding force between the rock formation is very low, general bolt Measures of anchoring ability is limited, if the roof collapse induced by will easily.So to solve this problem, we have to adopt the anchor belt net with anchor cable group Support technology, this technology is the use of bolt, steel band, metal net work together, to consolidate the top, to maintain the integrity of the roof to prevent collapse Trapped, and because the anchor cable can take some load of the rock, then more solid the roof. 3 The caving mining gateway uses the soil nail anchor combined support Fully-mechanized working face in two consecutive low compressive strength of the surrounding rock roof, and once under pressure, is prone to falls off phenomenon.For instance,By several kinds of in-situ stress, under the joint action of the top-coal is easier abscission of consequences, the unit weight of several kinds of in-situ stress were the top strata pressure,Geological tectonic stress and mining stress concentration.Therefore, in order to avoid the loss, we have to use bolt support measures, still need to add anchor cable, make whole To the roof rock of coal seam is more stable.In general, join in rock anchor cable length from 1 to 1.3 m, and the distance between layers of 4 ~4.8 m. 4 at the end of the fully-mechanized face mining anchor net supporting Geometric volume is larger, due to the similar working equipment tonnage is heavier, so want to work harder for removal process, need to empty Is very wide, between the removal of the maintenance of the standard is higher, so the application of anchor net supporting technique to solve this problem.By using this technology, not only the effect is obvious,Advanced technology, reasonable and convenient construction and economy. (3) for bolt and roof bolt, to follow the head-on avoid due to long time don't support roadway to fold to help. (4) when the drift Angle changes, can be adjusted through the roof in the middle of soil nail supporting, and the distance from center line to meet the technical specification.

The function of the soil nail is to provide tensile resistance, therefore the pull-out capacity of the nail is of major interest. The design capacity is verified on site by conducting pull-out tests in conjunction with the installation.
The principle of soil nailing is that rod shaped reinforcements, so-called soil nails, are installed in the undisturbed soil in order to increase the tensile and shear strength. As a result a composite body is created from the existing soil mass which is comparable to a gravity retaining wall in terms of its bearing behaviour, which can take on external forces.
Soil nailing can be used to stabilise terraces, deep excavations, slope faces, to stabilise existing slopes and strained soil masses during underpinning with any wall inclination. Here, you have to differentiate between temporary and permanent stabilisation. In many applications it proved to be the only economic solution.
Soil Nailing offers cost savings over demolition and rebuild alternatives and a soil nailing scheme will be less disruptive than these approaches.
Soil Nailing works by using soil nails to strengthen an existing surface or structure. Soil Nail techniques include both hollow bar self-drilling and solid bar methods, with installation in soft soils and weathered rock strata. A soil nailing scheme will also often require a range of structural, erosion control and aesthetic facing solutions to suit both technical and finished appearance requirements.
Soil Nails and Soil Nailing maximise available land usage and can minimse the interruption inherent in alternative approaches. Soil Nailing is especially effective in areas of environmental or archictectural sensitivity, refer to our case studies. Soil Nails have particular applications in areas of restricted access such as railway loactions and highways where soil nailing is often used to strengthen and stabilise embankments and cuttings.

Soil nailing as a construction technique has been found useful in some places abroad to reinforce the loose soil on slopes. The technology envisages drilling of holes in the slope and installing of steel rods and grouting them with concrete to literally nail the soil.
Landslide is a common natural disaster around the world. Many human loss and injuries occur due to different types of landslide. Through the last couple of decades, different kind of landslide preventive measures had been developed for reducing the hazard. Each preventive measure has its unique technique and application benefit. One of the most common slope stabilization methods is soil nailing.
