【摘要】 南中国海广泛分布着生物碎屑成因的钙质土。以相对破碎 B_r 为颗粒破碎的评价指标,在三轴试验条件下,分析了颗粒破碎对钙质土最大有效主应力比（σ′₁/σ′₃）_max、最大有效八面体应力比（q/p′）_max、八面体剪应变ε₅和抗剪强度指标φ′的影响。更多还原

【Abstract】 There are so many calcareous soils formed by biogenic scraps in South China Sea.Taking the relative breakage B_r,as evaluation index of particles crushing,the influences of particles crushing on the maximum effective principal stress ratio （σ′₁/σ′₃）_max,maximum effective octahedral stress ratio （q/p′）_max,octahedral shearing strain ε_s and shearing strength index Φ′ have been analyzed under the condition of triaxial tests.更多还原
