【摘要】 利用高精度静–动两用三轴仪(试样尺寸φ200 mm×510 mm)进行了砂砾料液化后静力再加载试验,研究了其应力应变特性。文中探讨了各种因素对砂砾料液化后静剪切强度的影响。结果表明:砂砾料液化后静剪切强度主要取决于围压,与液化前相对密度无关。更多还原

【Abstract】 By use of the medium scale dynamic triaxial apparatus(specimen size φ200 mm×510 mm),the laboratory tests on the sand-gravel after liquefaction were performed.The stress-strain responses and the main factors influencing the strength of liquefied sand-gravel were studied.It was shown that the strength of liquefied sand-gravel was mainly dependent on the confining pressure.更多还原
