In an attempt to represent this effect in a quantitative manner, summations of projected areas of contact surfaces of YZ- and XY-planes, being denoted by S_x and S_z respectively, is shown to be an useful index. Particularly, the ratio S_z/S_x which is determined by microscopic analyses of thin sections is believed to be one of the most important fabric features to determined some mechanical properties of granular sands. The ratio S_z/S_x has close relations with mobilized stress ratio as well as dilatancy rate. The maximum value of S_z/S_x at peak stress is determined not only by initial fabric but also by some other properties of granular particles. The process of fabric reconstruction is continuous and no gap can be observed between granular fabrics formed at pre-peak stress and those formed at peak stress. This continuous reconstruction of the initial fabric with the increase of axial strain is mostly due to the sliding along unstable contacts between grain particles and partly due to the rotation of grain particles.
