A simple method describing the effect of changing particle size distribution due to particle crushing is developed and applied to some practical geotechnical engineering problems. Firstly, past experimental researches on the particle crushing phenomena of granular materials due to stress change, temperature change and drying and wetting cycles are reviewed, and an elasto-plastic constitutive model for soils considering the effect of changing grading is then developed based on them. Validity of the proposed model is consequently checked through the comparisons with the past experimental results and results of elementary tests on steel slugs which exhibit significant crushing under a relatively low stress levels

提出了一种描述颗粒破碎对颗粒粒径分布影响的简单方法，并将其应用于实际岩土工程问题。首先，回顾了国内外关于应力变化、温度变化和干湿循环作用下颗粒破碎现象的试验研究，在此基础上建立了考虑级配变化影响的土的弹塑性本构模型。通过与以往的实验结果和在较低应力水平下表现出显著破碎的钢块的初步试验结果的比较，验证了所提出的模型的有效性
