STUDY ON THE DYNAMIC STRENGTH AND MODULUS OF SANDY PEBBLE SOIL
-
摘要: 通过砂卵石土动三轴试验,深入研究了砂卵石土动力特性,得到了砂卵石土的动强度和动模量在不同围压及固结应力比条件下的变化规律。试验结果表明,围压是动强度提高的重要影响因素,固结应力比不同的条件下,动强度及动模量变化也较大。Abstract: Studying the dynamic characteristics of sandy pebble soil by using the dynamic triaxial tests, it is discovered that the varying regulation of the dynamic strength and modulus of sandy pebble soil under different radial pressure and consolidation stress ratio . The result shows that radial pressure obviously effect the dynamic strength and modulus, it is also big that the change of dynamic strength and modulus under different consolidation stress ratio.
