5As for creep of the marine soft soil, the micro-mechanism of one-dimension creep is proposed: Under slight load, the initial bone strength and rank will be destroyed, while, as the time advances, deformation increases, void ratio decreases and inner particles move, bonding among particles become tight and the structure changes, and then the restitute of the old structural damage exceeds the new one. Consequently, creep will trend towards decelerate steady state ultimately.

揭示了软土一维蠕变的微观机理：当土样受荷较小时，尽管土样初始结构要受到影响，某些颗粒连结强度、胶结性、定向排列性遭到破坏，但随着时间的增长，变形增大，孔隙比减小，土体内部颗粒发生位移，使得某些颗粒结构间的联结更紧，胶结因而逐渐恢复，定向排列性亦略有回升，从而使得结构缺陷的愈合超过胶结的破坏和新缺陷的形成，蠕变最后趋于减速稳定状态。
