Abstract: Most of the current soil treatment and ground treatment techniques do not take into consideration the original soil structure; instead, they enforce strong disturbances upon the soil by remolding soil structure at a great consumption of energy and a high cost. Based on the mini-scale structure of soil, the authors classify ground treatment into three types derived from the mechanical property of reinforced bodies and the structural varying angle of reinforced soils, and then further divide them into two subcategories derived from enforceable paths of soil treatment techniques. The interaction of reinforced bodies and soils along with the structural effects of soils are emphasized in this classification. If the original strength of soil can be fully utilized, and supplemental structural strengthening can be designed and implemented on the basis of primary structural form of the specific soil to be treated, it will reduce project costs by conserving energy and minimizing environmental impacts and disturbance of the soil.
