【摘要】 在多年冻土区开展物探工作时不能完全照搬非冻土区的物探方法所取得的成果,本文对探地雷达在多年冻土区工程地质勘察中的应用效果进行了理论分析与对比研究,摸索出一套适合冻土区勘察的物探野外工作程序和资料处理方法,最终达到准确、快速地了解冻土区内及冻土体内诸多关键参数的目的。对探地雷达在黑北公路与青藏公路的多年冻土区实际勘察中的应用效果进行了分析,并与钻探结果进行了对比。结果表明,探地雷达在多年冻土地区公路勘察中具有良好的效果。研究成果对于类似地区的工程勘察具有一定的参考意义。更多还原

【Abstract】 Geophysical exploration work is more complicated and various in permafrost region than it in non-permafrost region.In this paper,the application effect in engineering exploration is theoretically analyzed and comparatively studied.A set of work process and treating method for exploration of permafrost are put forward.Finally,the aim is reached,which a series of key parameters are accurately and quickly known.Furthermore,the application effect of ground penetrating radar in Hei-Bei highway and Qinghai-Tibet highway is analyzed and the result is compared with the one of the boring exploration.The results indicate that it is useful to settle practical engineering problem and realize scientific problems for permafrost region and it can be referred in other engineering practice.更多还原
