The invention relates to a method for testing the perpendicularity of an underground diaphragm wall. The method comprises the following steps: establishing a diaphragm wall model according to design information of the underground diaphragm wall; the underground diaphragm wall is scanned through ultrasonic detection equipment, and refracted ultrasonic signals are collected; drawing an ultrasonic image according to the ultrasonic signal; and comparing and analyzing the ultrasonic image and the diaphragm wall model to judge the perpendicularity of the underground diaphragm wall. 本发明涉及一种地下连续墙垂直度测试方法，包括如下步骤：根据地下连续墙的设计信息建立连续墙模型；通过超声波探测设备对地下连续墙进行扫描和收集折射后的超声波信号；根据超声波信号绘制超声波图像；将所述超声波图像和所述连续墙模型进行对比分析，以判断地下连续墙的垂直度。
