| 摘 要： | 土的剪切波速是岩土工程领域的一个重要参数.建筑场地类别划分、地基饱和砂土液化判别、地震反应分析等都依赖于剪切波速,由于其重要性,对它的测定技术和精确程度应重点研究.针对工程中广泛采用的单孔法剪切波速测试,提出了一种基于互相关函数计算土层剪切波速的优化算法.克服了传统数据处理方法中经常遇到的负波速、波速数值明显过大或过小和同一土层各测点波速差别较大等4种不合理因素,提高了数据分析的精度和效率. |

| Abstract: | Soil shear wave velocity is an important parameter of earthquake engineering. Classification of engineering site sort, reassessment of saturated sandy soil liquefaction and subsoil earthquake response analysis all depend on subsoil shear wave velocity. An optimized approach for single-hole method of shear wave velocity measurement is presented. The approach overcomes main irrationalities of minus velocities, over-large and over-small velocities and large velocity differences among measuring points in the same layer of traditional analysis method, improves the data processing precision and efficiency of single-hole method. |
| Keywords: | shear wave velocity single-hole method correlation function optimized approach |
