目前国内使用的十字板一般分机械式和电测式两种,陆域十字板剪切试验的有关研究资料认为两者的测试值一般相差约为10～20%,但在水域进行试验时,由于易受风浪、潮流等多种客观因素的影响,这两种十字板剪切仪的试验情况又会怎样呢?本次选择上海和天津两处试验区,分别在勘探船搁浅与浮起两种不同作业情况下,进行机械式与电测式十字板剪切试验的对比研究。 At present, the cross used in the country is generally divided into two mechanical and electrical measurements. According to the relevant research data of the land cross-cut test, the test values ​​of the two generally differ by about 10-20%. However, in the waters, Due to the influence of many objective factors, such as wind and waves, tide and so on, what will happen to the test situation of the two types of cross-cut shears? This time, two pilot areas in Shanghai and Tianjin were selected, Under different operating conditions, a comparative study of mechanical and electrical test of cross-plate shear test.
