摘要
目前的土质加固与地基处理技术,大都摒弃土体原有结构不用,或实施强力重新构造土体的结构,以耗费大量的能 量、费用为代价。基于土的细观结构,从加固体的力学特性以及加固土体的结构变化角度对地基处理类别进行三类划分、按 土体加固技术的实施路径进行二类划分,目的是更多地关注加固体与土的相互作用、重视土的结构作用。若能在加固时充分 利用土体的原有强度,在已有的土体结构形式上实施结构上的补强,在理论上将使能量使用更经济、从而节约工程造价,而且 将减少对环境的影响和扰动。
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.
