随着传感器技术的发展以及新型探头的出现,静力触探试验所能提供的土性参数和应用范围日益扩大。用先进的静力触探设备测试计算出的岩土体剪切波速同单孔法测试结果相吻合,说明了SCPT测试方法的有效性。为适应常规静力触探设备的需要,对砂性土和粘性土分别建立了剪切波速同其它静探指标的关系式,同时,提出了两个适用于各类土体的统一公式。用该公式计算的剪切波速结果同实测结果较为一致,有助于工程实践中剪切波速的合理确定。
With the development of sensor technology and the advent of new probes, the static parameters and the range of applications that can be provided by the static probe test have been expanding. The shear wave velocities of rock and soil calculated by the advanced static probe equipment coincide with those of the single hole method, which shows the effectiveness of the SCPT method. In order to meet the needs of conventional static probe equipment, the relationship between shear wave velocity and other static parameters is established respectively for sandy soil and cohesive soil. At the same time, two uniform formulas for all kinds of soil are proposed. The shear wave velocity calculated by this formula is consistent with the measured results, which is helpful to the reasonable determination of shear wave velocity in engineering practice.
