【摘要】 瑞利波勘察技术近几年在工程勘察及工程检测中得到了广泛的应用。为满足勘探目的、达到最佳勘探效果,工作前应进行现场试验,遵循从已知到未知的原则,通过试验初步了解和掌握测区地层的地球物理条件,根据勘探任务目的与要求,结合测区实际地质、地形和物性条件,确定观测点点距、道距、偏移距、激发方式和仪器参数等,选择最佳观测窗口,以获得最佳观测效果。笔者列举了瞬态瑞利波勘探方法的几个应用实例,包括抛石体厚度探测、划分软弱夹层、滑坡勘察及地基振冲处理效果评价等,效果较好,经济适用,说明了瞬态瑞利波在浅层工程地质勘察中具有很大的应用潜力。更多还原

【Abstract】 Raleigh wave exploration has been widely used in geotechnical investigation and geotechnical inspection in recent years.For the purpose of meeting the need of the exploration and achieving the best exploration result,we should make in-site test before the work,following the principle "from the known to the unknown",preliminarily understand stratigraphic and geophysical conditions of the surveyed area through the test,determine the distance between points,the distance between channels and the distance between deviations,the excitation ways and the instrument parameters and select the best observation window according to the aim and requirement of the exploration task in combination with the geological,topographic and physical conditions.Engineering examples on the application of transient Raleigh wave exploration are given,and it is shown that the Raleigh wave exploration method has great application potential for inspecting the shallow ground.更多还原
