浙江软土地区不同应力路径下的土体模量研究

Effects of stress path on compression modulus of Zhejiang soft soil

通过室内土工试验,研究了单一加载、加载—卸载、加载—卸载—再加载三种不同应力路径下,土体模量的变化规律,结果表明:三种不同路径下的土体模量均呈现出随取样深度增大而提高的趋势,且深度越大,提高幅度也会越大。

By the indoor civil tests,the paper researches the change law for the soil modular under three stress paths including the single loading,loading-unloading and loading-unloading-reloading,and proves by the result that the soil modular under the three paths can increase along with the increasing depth of the sample and the deeper it goes,the larger the extent will be.
