立足于介质差异，考察桩周介质、桩周介质层、桩底介质的差异对低应变反射波法检测结果的影响，得到如下结果：介质差异会极大地影响波的传递和波的桩底反射波幅。对误判实例进行解析，提出用低应变反射波法测桩前务必掌握成桩地质柱状图和桩体混凝体强度，以减少导致误判的因素。
立足于介質差異，攷察樁週介質、樁週介質層、樁底介質的差異對低應變反射波法檢測結果的影響，得到如下結果：介質差異會極大地影響波的傳遞和波的樁底反射波幅。對誤判實例進行解析，提齣用低應變反射波法測樁前務必掌握成樁地質柱狀圖和樁體混凝體彊度，以減少導緻誤判的因素。

Based on medium differences,this paper investigates influences of differences in peripheral media of piles,medium layers around piles and media on the bottom of piles on detection results of the low-strain reflected wave method and obtains the following results:medium differences will greatly influence transmission of wave and the amplitude of reflecting wave on the bottom of piles.The paper analyzes misjudged examples and proposes that geological histograms of piles and concrete strength of piles must be mastered prior to measurement of piles with the low-strain reflecting wave method to reduce factors of misjudgment.
