摘要
贵州红粘土受酸液作用后,其无侧限抗压强度降低,其中所含的胶结物质──针铁矿的含量减少,二者有函数关系。本文通过针铁矿与盐酸反应的化学动力学参数的测试,得到了针铁矿的含量与时间的函数关系。并对该土的力学特性变化作出了时间预报。其它类似的环境因素影响岩土介质时,也可用本文的原理和方法来预报其力学特性。
After Guizhou red clay is reacted with chlohydric acid,the unconfined compression strength and goethitecontent of the clay decrease. And there is a function relationship between them. In this paper,the functional rela-tion between goethite content and time is derived from determining chemical kinetics parameters of reaction ofgoethite and chlorhydric acid The forecast for the change of mechanical properties with time has been given accord-ing to the chemical kinetics. The principle and method in this paper can also be used to prediction of mechanicalproperties of soil and rock affected by similar environment factors.
