地质雷达在上三高速公路护面墙检测中的应用

上三高速公路K224+720 ～ K225+020左山体自2008年以来,每逢大雨,该山体第二级坡面的长约20m范围内有局部泥沙从泄水孔带出,在对护面墙及碎落台的跟踪检查中,由于局限于目前管理单位的检测设备,未发现空洞、变形.为确保高速公路的安全畅通,此次采用地质雷达对该山体的护面墙进行检测,可快速了解护面墙的厚度、密实度等质量情况.

Application of Geological Radar in Detection of Shangsan Highway Retaining Wall

Whenever it rains, theie have been sediments flowing out of the drain holes on the second step of the slope since 2008. This phenomenon raniged along the left side of Shangsan highway from K224 ＋ 720 to K225 ＋ 020 lasting about 20m. Due to the limitation of testing equipment, no cavity or defolmation were found during the examination of retaining walls and drop steps. To ensure the smooth and safety of highway,, geological radar was used to detect the cavity on the highway retaining wall along the Shangsan highway K224 ＋ 720 to K225 ＋ 020 on left the mountain. A quick overview of the retaining wall thicl~ness, density, and quality can be obtained by this method.
