本文采用鲁布革和天生桥坝科红土,研究了红土干燥脱水对物理力学性质的影响。试验表明,红土干燥脱水后性质指标有变化,且具有不可逆性。文中对其原因进行了分析,并指出,忽略了红土的这一特性,试验结果将不仅是一般误差问题,而且可能导致工程上的一些错误判断。 In this paper, Lubuuge and Tianshengqiao red clay were used to study the effect of drying and dehydration of red soil on the physical and mechanical properties. The test shows that the properties of the red soil after drying and dehydration have changed and are irreversible. The paper analyzes the reasons and points out that neglecting this feature of laterite, the test results will not only be a general error problem, but also may cause some misjudgments in engineering.
