地质雷达技术在市政工程勘察中的应用研究

Application research of ground penetrating radar technology in Municipal Engineering Prospecting

由于市政工程的特点,常规的勘察手段有时会有局限性。地质雷达具有高效、无损、可靠、工作条件宽松等特点,在工程领域中的应用日趋广泛。某市政工程地下通道进行岩土勘察,首先需要查明勘探孔位置处的地下管线分布情况,进而查明工程地质条件。常规的钻探手段,现场暂不允许采取施工围挡等措施。为了满足工程的工期、质量要求,通过采用地质雷达技术,良好地解决了地下管线分布情况以及补充完善勘探孔之间的地质剖面,保证了工程的顺利进行。实践证明了地质雷达技术在市政工程中具有良好的应用效果和应用价值。

Due to the characteristics of municipal engineering,the conventional survey methods sometimes have limitations. Ground penetrating radar(GPR)is widely used in the field of engineering because of its advantages of high efficiency,non-destruction,reliability and loose working conditions.The geotechnical investigation of the underground passage of a municipal engineering project needs to find out the distribution of the underground pipeline at the location of the exploration hole,and then find out the engineering geological conditions.Conventional drilling methods,temporary construction site is not allowed to take measures such as construction block.In order to meet the project schedule and quality requirements,through the use of geological radar technology,a good solution to the distribution of underground pipelines and improve geological exploration hole between the section,to ensure the smooth progress of the project. Practice has proved that geological radar technology has good application effect and application value in Municipal Engineering.
