利用三轴试验进行碎石基层的力学性能研究,探讨加载速率对碎石基层静力学性质的影响,分析不同加载速率对级配碎石弹性模量、峰值强度及残余强度的影响,建立加载速率与弹性模量、峰值强度及残余强度之间的定量关系描述方程。研究结果表明:级配碎石的弹性模量、峰值强度以及残余强度均随加载速率的增大而增大;函数E=a_1v~(b_1)能够较好地描述弹性模量E与加载速率v之间的关系;峰值强度、残余强度与加载速率符合线性关系。

The mechanical characteristic of the grading macadam was studied, and the influence of the loading velocity was analyzed. The influences of the loading velocity on the elastic modulus, peak strength and residual strength of grade were analyzed, and the relationship equations among loading velocity, elastic modulus, peak strength and residual strength of grading macadam were built. The results show that elastic modulus of grading macadam, peak strength and residual strength increase with the increase of the loading velocity. The equation E=a1vb1...
