When carrying out dialyzability assay, it is necessary first to it is determined that the optimal dialysis time corresponding to the experiment soil body.The dialysis time is too short, soil sample Suction is not up to balance with PEG solution suction;Dialysis overlong time, then the PEG macromoleculars in solution be highly likely to enter in film, And pellicle is easily destroyed, it will cause that the suction value measured is less than normal, moisture content is bigger than normal.Therefore, determine in test used The optimal dialysis time of soil, then follow-up test is carried out with this.
2nd, the fitting of soil-water characteristic curve
Using Fredlund- Xing models, simulation fitting is carried out to experimental data, can obtain testing soil body continuous and derivable SWCC。
3rd, the use of penicillin
Microbes make pellicle reduce the life-span with the increase of soak time in water, therefore the addition of penicillin is essential.
