桂林红粘土的土工试验指标关系分析

Soil Index Analysis of Guilin Red Clay

对桂林市51个工程项目的645个红粘土试样的土工试验指标值进行了统计分析,总结了桂林红粘土的物理、力学性质指标随深度变化的规律,得出了红粘土相关物理性质指标间、力学性质指标间、物理与力学性质指标间的变化关系式及相关线性方程.据此对由不可避免因素引起的土工试验指标异常,可进行定性的判断或定量的校正.通过在工程实践中检验,经校正得出的值能很好地反映土的原本性质和各指标间的内在联系.

The soil test indices of 645 red clay soil samples in 51 projects of Guilin are analyzed by statistical methods. Such achievements are detailed in the following： the characteristics of physical and mechanical indices with a change in depth; the nonlinear and linear equations describing the relationships of relevant physical indices, mechanical indices between physical and mechanical indices. The abnormal indices caused by unavoidable reasons can be judged or calibrated quantitatively. The calibrated value can reflect the natural characteristics and relationships between these indices of soil through engineering practice.
