摘要:
土体结构性的数学模型是21世纪土力学的核心问题,是决定土的性质的重要内在因素.基于综合结构势的概念,采用应力结构性参数和应变结构性参数,通过q=0和等p 剪切试验,修正K-G 模型.为检验模型的可靠性,以海口某实际工程为依托,应用修正的K-G 模型进行模拟计算路基沉降,并与实测值进行对比, 发现此本构模型适用于海南红粘土这一类土质,具有实际意义.
Abstract:
The mathematical model for the structured soil is the key problem of soil mechanics in the 21st century, an important internal factors for soil properties. In this paper, the stress of structural parameters and structural parameters of strain based on the concept of comprehensive structure potential is used to modify K-G model by q=0 and P shear test. To check out the model reliability, the modified K-G is used for the model simulation calculation of embankment settlement based on an engineering practice in Haikou and is compared with the measured values. It is found that this constitutive model is applicable to this type of Hainan red clay soil, with practical significance
