| 中文摘要: |
| 通过室内大型三轴试验激光微小应变测试结果与现场波速试验测试结果的比较，论证了在一定条件下，最大动剪模量压力效应关系曲线可以通过室内试验获得，也可以通过现场波速试验经换算获得，建议在实际应用中将两者综合考虑。从而为深厚覆盖层地基上高土石坝地震动力反应分析提供更为可靠的依据，为深厚覆盖层工程特性的进一步研究提供参考。 |
| 英文摘要: |
| The experimental result of maximum dynamic shear modulus by using large-scale cyclic triaxial testing machine equipped with laser strain measurement devices is compared with the field test data obtained from wave velocity measurement. It shows that, under some specific conditions, the plot for pressure effect of maximum dynamic shear modulus obtained from experiment is approximately the same as the calculation result according to the wave velocity. It is suggested that, in practice, the adopted modulus must be determined by comprehensively considering the results obtained from experiment and field test. |
