| 摘 要： | 将含钙量较高的粉煤灰与普通粉煤灰混合,进行相关的工程力学性质试验。试验结果表明:粉煤灰混合料的最优含水率、最大干密度与高钙粉煤灰的掺加比例线性相关;粉煤灰混合料的无侧限抗压强度、水稳定性能够满足路基工程的要求,且具有一定的抗拉能力;粉煤灰混合料的抗压回弹模量随压实度线性增大,一定龄期的粉煤灰混合料压缩模量明显大于散粒体粉煤灰的压缩模量;养生后土工网对粉煤灰的内摩阻力迅速增大,界面处的似摩擦系数增大。

| Abstract: | The experiments of engineering mechanics are made on the mixtures composed of high calcium flyash and general flyash.The optimum water content and maximum dry density of the mixtures are related to the content of the high calcium flyash,the unconfined compression strength and water stability of the mixtures can satisfy the subgrade engineering,and the mixtures have a definite tensile ability.The modulus of resilience increases with the compactness of the mixtures linearly,and the compressive modulus of the ... |
