Along with the progress of materials and structures, deflection and axial load conversion which is the important and basic problem still need further investigation and discussion for reasonably revision.
However, considered mechanics model, subgrade module, materials behavior and parameter have certain difference between the theory and the actual condition, Design Specification adopted the correction coefficient F (see Eq.1) [11,12], but the F value by Eq.2 is usually less than 1, when the deflection value is 30(0.01mm) is 0.58; when the deflection value is 50(0.01mm) is 0.7; when the deflection value is 130(0.01mm) is just 1.01.

In the 1990s, SUMF was synthesized by Lahalih as sand-fixing agent [3]; Wei Xiucheng developed LZU series sand-fixing material, conducted field experiment and obtained good results [4]; Zhang Hua applied macromolecule material YDL to sand-fixing, but these materials were too expensive [5].
It also had good application and development prospects because of its widely used raw materials and low costs.
