摘要
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,mechanical-logging and electrical-logging are two ways for vane shear test at home.Relational research indicate that discrepancy between testing values of terrestrial vane shear test is about 10～ 20%.However,water vane shear test is obviously affected by many external factors,such as stormy waves and tide.What is the difference between the two kinds of vane shear test under water condition? In this study,Shanghai and Tianjin were choosed as two testing sites.Contrast research of mechanical-logging and electrical-logging vane shear test is carried when drilling barque is grounded or floated.
