中文摘要	通过对黄土结构性及其对黄土力学特性影响的深入分析,认为黄土颗粒之间的力有联结力和摩擦力两种。联结力属于短程力,包括化学胶结力、土颗粒间的分子引力、薄膜水和毛细管水产生的吸力,这些力形成了黄土的联结结构强度。摩擦力属于远程力,是土体受力时土颗粒之间有相互错动、移位、重新排列的运动或趋势时才产生的阻止土体变形的力,包括颗粒之间的摩擦力和咬合力,这种力形成了黄土的摩擦结构强度。黄土的结构强度就是由联结结构强度和摩擦结构强度组成的。提出了黄土联结结构强度、摩擦结构强度、压密强度等的定量化概念。
英文摘要	Through the comprehensive and in-depth analysis on the structural of loess and its impact on mechanical properties，it was put forward that the forces between the loess particles made from the connecting force and the friction． The connecting force is a short-range force that including chemical cementing force，molecular gravity between soil particles film water and capillary water produce and suction produced by film water and capillary water，these forces join to form the connection structural strength of loess． The friction is a long-distance force that is to stop soil deformation when the movement or trend of each dislocation，displacement，re-arranged between the soil particles occurred，including friction and bite force between particles，this force formed the friction structural strength of loess． The structural strength of loess is composed of the connection structural strength and the friction structural strength． The quantitative concept of the connection structural strength，the friction structural strength and the compaction strength are put forward．
