提高双线法黄土湿陷性试验成功率的研究

摘要

针对铁路项目中双线法黄土湿陷性试验成功率低的问题，从整体上对试验进行了研究，提出从现场取样运输、试样制备、仪器检定、试验过程及数据采集处理等方面进行改进，以提高黄土湿陷性试验的成功率。%For the problems of the low success rate of loess collapsibility test by double-line method on railway project, taken from the whole study of the test and offered improvements, include the sample transport, sample preparation, instrument calibration, test procedures and data acquisi tion and processing, and succeeded in raising the success rate of loess test.
