地下管道交叉部位土体密实程度是影响管道生存环境的重要因素,但当前探测技术水平对于地下管道交叉部位的土体密实度探测准确性较低。基于此,采用标准贯入度法和弹性波声波透射法进行探测。采用该方法对山西境内某高速公路地下管道交叉部位的土体密实度进行探测,并根据土体纵波波速描绘探测区域土体的等值像图和等值线图,较直观地描述了探测区域土体的密实程度。 The degree of soil compaction at the intersections of underground pipelines is an important factor that affects the living environment of the pipeline. However, the current detection technology has a low accuracy in detecting the soil compaction of the intersections of underground pipelines. Based on this, using the standard penetration method and elastic wave acoustic transmission method for detection. This method is used to detect the soil compaction of the underground pipelines in an expressway in Shanxi Province. According to the longitudinal wave velocity of soil, the equivalent image and contour map of the soils in the survey area are described. The detection area Soil density.
