ground surface effect

The effect of surface wettability of porous media on the plugging properties of LPS was studied through the ground glass model, quartz sand-packed tube and artificial core plugging experiments.

采用毛玻璃模型、填充砂管和人造岩心封堵实验，研究了多孔介质的表面润湿性对交联聚合物溶液（LPS）封堵性能的影响。

The experiment indicates that wind itself is of weak effect on ground surface erosion, so that the soil crust may not be destroyed even under great wind velocity.

实验表明：净风对土表的风蚀作用微弱，即使在遭到大风吹刮时，土表的结壳仍不易受到破坏。

For the conventional cement base surface, liquid curing agent for sealing, can enhance the surface wear resistance, strength and impermeability, prolong the service life of ground and using effect.

对于常规水泥基地面，用液体固化剂进行密封加固，可以增强地面的耐磨性、强度和抗渗能力，延长地面使用寿命和使用效果。
