摘　　要：公路等线路工程会穿越特殊土地段,而工程勘察中难以准确查明土层的分布范围及深度。因此,为提高特殊土路基设计质量、减少工程变更,对于地表几米深浅层特殊土,需找出一种原位快速测试手段。经过工程实践,与其他测试手段对比,采用可变能量动力触探仪可快速、高效又经济地探明浅层特殊土的分布及其状态。Highway type project sometimes needs to pass through special soil zone, but it is difficult to ascertain the range and depth of soil layer by geoteehnical investigation. Therefore in order to improve design quality of special soil subgrade and reduce variation, it is neeessary to find a kind of quick in-situ test for superficial special soil within a few meters deep. Th variable energy dynamic penetrometer can investigate the compared with other testing methods, which proves that the rough the engineering practice, it finds that range and depth of superficial special method is rapid, efficient and cost-effective.
