快速固结实验与标准固结实验结果的对比分析

以粉质黏土为研究对象,以饱和度为影响条件,对比标准固结实验与快速固结实验结果,探讨快速固结实验代替标准固结实验的可行性及其适用条件。实验结果表明:对于气连续型的粉质黏土,可以在较低荷载作用下用快速固结实验代替标准固结实验;对于过渡和封闭型的粉质黏土,可以在较高荷载作用下用快速固结实验代替标准固结实验。在相同荷载作用下,对于气连续型粉质黏土,可以在饱和度较低情况下用快速固结实验代替标准固结实验;对于过渡型和封闭型土体,可以在饱和度较高情况下用快速固结实验代替标准固结实验。其研究成果可为提高类似土体固结实验提高效率提供参考和技术支持。

Rapid consolidation experiment with standard consolidation the comparison and analysis of experimental results

Taking silty clay as the research object, the feasibility and applicability of the rapid consolidation test in place of the standard consolidation test are discussed. The experiment results show that the gas continuous silty clay in low load by rapid consolidation experiment instead of the standard consolidation test; for the transition and closed type silty clay, can play a role in the high load by rapid consolidation experiment instead of the standard consolidation test. Under the same load, the gas continuous silty clay, in the case of low saturation by rapid consolidation experiment instead of the standard consolidation test; the transition type and closed type soil, in the case of higher saturation by rapid consolidation test instead of the standard consolidation test. The research results can provide reference and technical support to improve the efficiency of soil consolidation experiment.
