| 摘 要： | 鉴于目前常用的剪切波速测试法、液性指数法和原位测试法等进行砂土震动液化的复判方法存在弊端，本文提出标准贯入击数--锥尖阻力复判法( qc--N 复判法) 及瑞利波法等间接测试击数的方法进行砂土震动液化判别。通过理论计算及实例验证表明，判别结果与相对密度法测得结果一致，同时具有工作效率高、生产成本低的优点，有较高的实际应用价值。

| Abstract: | Because the shear wave velocity testing,liquid index and in situ testing methods have shortcomings in judging the vibrate liquefaction of sand,qc——N discriminance and Rayleigh wave methods are proposed to distinguish sand vibrate liquefaction by testing blow count indirectly.Theoretical calculation and examples show that its results are the same with the testing results of relative density method.Meanwhile,it has higher efficient in work,lower cost in production,and more valuable in practical applications. |
