Abstract This paper presents a review of particle breakage in granular soils by comprehensively summarizing the measurement of particle breakage, the fundamentals of particle breakage, the soil mechanics on particle breakage, the theoretical models of soil incorporating particle breakage. In the measurement of particle breakage, most particle breakage indexes were proposed according to the change of soil grading. The increase in the particle-surface area and probabilistic method were also employed to quantify particle breakage. In the fundamentals of particle breakage, the crushability of granular soil is mainly related to the physical nature and mechanical properties of soil, the stress-strain state on soil and the surrounding environment on soil, which were always interpreted by the energy theory and fractal theory. In the soil mechanics on particle breakage, particle breakage resulted in impairment of dilatancy behavior of soil to become a more contractive soil, significantly influencing the shearing, dilatancy, and state behavior of soil. A number of constitutive models of granular soils incorporating particle breakage were proposed by the elastoplastic theory, the bounding surface theory, the disturb state concept theory, the continuum breakage mechanics theory, and the generalized plasticity theory for interpreting the influence of particle breakage on soil behavior.

颗粒土壤中的颗粒破碎：综述

摘要 本文综合总结了颗粒破碎的测量、颗粒破碎的基本原理、颗粒破碎的土力学、颗粒破碎土壤的理论模型，对颗粒土壤中的颗粒破碎进行了综述。在颗粒破碎测量中，大多数颗粒破碎指标是根据土壤级配的变化提出的。颗粒表面积的增加和概率方法也用于量化颗粒破损。在颗粒破碎的基本原理中，粒状土的可碎性主要与土的物理性质和力学性质、土上的应力-应变状态以及土壤周围环境有关，一直被能量理论和分形理论解释。 . 在颗粒破碎的土力学中，颗粒破碎导致土的剪胀行为受到损害，成为更收缩的土，显着影响土的剪切、剪胀和状态行为。弹塑性理论、边界面理论、扰动状态概念理论、连续体断裂力学理论和广义塑性理论提出了许多包含颗粒破碎的颗粒土本构模型，用于解释颗粒破碎对土体行为的影响.
