Vibration-assisted static sounding method and application
The invention provides a vibration-assisted static sounding method and application, and belongs to the field of geotechnical engineering investigation in-situ test. The vibration-assisted static sounding method comprises the following steps of step 1, positioning and preparing a vibration-assisted static sounding instrument; step 2, performing static press-in of a probe, and reading data, whereinthe press-in speed is 0.015 to 0.025 m/s, and the soil press-in resistance is inversely proportional to the press-in speed; step 3, performing vibration press-in of the probe, and recording the vibration completing depth; step 4, alternating the vibration type press-in and the static press-in, and changing the press-in into static press-in after the vibration type press-in enters a next cycle; andstep 5, exporting and correcting the data, and multiplying the data of a vibration part by different regulation coefficients according to different depths to finally obtain the test data after the vibration-assisted static sounding correction. The vibration-assisted static sounding method has the advantages that the vibration-assisted static sounding instrument is specified; meanwhile, after thedata is processed, the effect of direct utilization is achieved; and the expanded application range of the vibration-assisted static sounding technology is realized.
本发明提供了振动辅助式静力触探方法及应用，属于岩土工程勘察原位测试领域，包括以下步骤，S1、振动辅助式静力触探仪的定位和准备；S2、探杆的静力压入和数据读取，压入速率在0.015～0.025米每秒，土质的压入阻力与压入速率成反比；S3、探杆的振动式压入，并记录振动结束深度；S4、振动式压入与静力压入的交替，振动式压入进入下一个循环即改为静压；S5、数据的导出和修正，将振动部分的数据根据不同深度乘以不同的调整系数，最终得到振动辅助式静力触探修正后的测试数据。本发明规范振动辅助式静力触探仪，同时将数据处理后达到直接利用的效果，实现振动辅助式静力触探技术的扩大应用范围。
