Based on engineering practices and relevant experimental data for a long times, and in point of view of deformation and loading of soil anchor-bar in the different conditions, this paper analyzes and studies deformation and rigid calculation formulae of difference soil anchor-bars.

According to the depth of the circumstances of the excavation,The bored piles and soil anchor-bar are adopted.

Through the project example,the characteristic of the soil nailing & shotcreting technologies was introduced.

The nail-dog and rock-bolt technique is often used in the supporting construction of such complicated slopes as artificial fill, sandy graves strata, sand deposits and muddy soil.
