The Effect of Nail Inclination of soil Nailing Structure of vertically Faced Wall
For the soil nailing, recently, its application is expanded, but there is no officially approved method to design it yet. Furthermore, there are a great number of design valuables in soil nailing, it is also used without clear data under the situation that uncompleted detailed research on the sensibility between design variables. Especially, there has no deal with the installation angle of the nail - the major contents in this study. Therefore, this study based on the theoretical estimation analyzed safety rate about the angle of the nail, unit weight, adhesive force, internal friction angle and tensile farce worked on nail in the case of the rear of pond side is both horizontal and perpendicular. As a result, it could be verified that the safety rate increased on every cases in the situation of the nail installation angle was in upward direction than in downward direction.
Based on the landscape characteristics of city block,a grade appraisement index system on effect of aesthetic of city block was point-ed out.And based on the system,the indistinct synthesis appraisement model was pointed out.The garden landscape effects of aesthetic per-ception of the People’s Hospital of Fangcheng County were appraised by using this model.
