Model experimental study on GFRP anchor reinforcement and soil deformation

The article presents the analysis of the results of field experimental study of the effect of the contact surface forms of the foundation on the deformability of subgrade. Experimental data show peculiarities of intensely deformed state of subgrade loaded on a curved concave contact surface. Stiffening of the base in this case is due to higher modulus of deformation of soil deformation in the core base, due to the additional lateral compression of soil, relating to a form of the contact surface.

Soil Dilatancy

The means of current experimental study on expansive soil dilatancy primarily count on triaxial apparatus and compression apparatus. The narrative revealed in the article is in relation with expansive soil trial by means of CBR test, with outcome linked to regulation among swelling amount rating with time, initial moisture content, and dry density, which leads to high value associated with implication for predicting expansive soil deformation with moisture.

Illumination Mode

The tilted beam illumination method is used to improve the resolution comparing with the axial illumination mode. Using this advantage, a restoration method of several tilted beam images covering the full azimuthal range was proposed by Saxton, and experimentally examined. To make this technique more reliable it seems that some practical problems still remain. In this report the restoration was attempted and the problems were considered. In our study, four problems were pointed out for the experiment of the restoration. (1) Accurate beam tilt adjustment to fit the incident beam to the coma-free axis for the symmetrical beam tilting over the full azimuthal range. (2) Accurate measurements of the optical parameters which are necessary to design the restoration filter. Even if the spherical aberration coefficient Cs is known with accuracy and the axial astigmatism is sufficiently compensated, at least the defocus value must be measured. (3) Accurate alignment of the tilt-azimuth series images.
