摘要
软土具有明显的地域特征、不确定性和变异性,选取大连某地区的软土土样,通过土工试验和线性拟合分析研究其各项物理力学指标的相关性,为大连某地区软土地基上的工程建设项目提供更为准确合理的设计参数。研究结果表明,大连某地区软土的工程地质性质较差、物理指标变异性小、力学指标变异性大,e-w和wP-wL之间呈线性相关,其他指标的相关性较差。
Due to obvious regional characteristic, uncertainty, variability of soft soil, Dalian some area soft soil is sampled to analyze the correlation of soft soil physical and mechanical indices through soil test and linear fitting model, which will provide more precise and reasonable design parameters for the projects constructed on Dalian some area soft soil foundation. It is shown in the research that Dalian some area soft soil is characterized with poor engineering geological quality, less physical index variability, large mechanical index variability, linear correlation between e-w and wv--WL, and poor correlations among other indices.
