柔性材料单位膨润土量早期快速测定方法研究

Research on Early Quick Measurement Method for Amount of Unit Swelling Soil

针对三峡工程二期围堰防渗墙浇筑柔性材料的检测质量和工期难以兼顾的问题，通过室内及现场试验研究，提出了材料配方中膨润土量的早期快速测定方法，并详细分析了影响该方法测试精度的主要因素，同时指明了改进方法。

For solving the contradictory problems on examination quality and construction period of flexible materials used in impermeable wall for 2nd phase cofferdam of the Three Gorges Project,by means of laboratory and field tests,an early quick measurement method for amount of unit swelling soil in the flexible materials is put forward.The primary factors affecting this method and improvement ideas are discussed.
