中文摘要：
古河道的存在与否直接影响到建筑的桩基类型。针对古河道与上层覆盖层之间存在较明显弹性差异的特点,采用地震映像法对某地区的潜在古河道进行了探测,对典型测线的地震波剖面图进行了分析,并通过钻孔对地震映像法的探测结果进行了验证,由此确定了古河道的走向。通过工程实例,说明了地震映像法在其测深范围内对古河道探测的有效性,地震映像法所得结论与地质结果、钻孔资料较吻合。
英文摘要：
The existence of the old channel directly affects the type of the pile foundations when people select a place to build a new factory.The article aims at exploring the potential ancient channel by seismic profiles interpretation,analyzing the profiles of the seismic waves of the typical lines and checking the exploration results from seismic profiles interpretation by drilling.Then,the direction of the ancient channel around the factory is located.All the ways are based on the variances between the ancient channel and the slipcover.The engineering projects illustrate that the seismic profiles interpretation is effective for the old channel detection in the range of depth measurement and the conclusion of seismic profiles interpretation is consistent with the geologic result and the borehole data.
