Experimental Study on Dynamic Water Scrubbing on the Surface of New Silt Dam Solidification Soil
[Purposes]In order to overcome the problem of silt dam overflow,it is necessary to determine the surface resistance of solidified soil to crushing through experimental research.[Methods]At the cur-rent stage,there are no corresponding equipment and method standards for water rushing tests on the sur-face of the solidified soil.Therefore,through the research and development of the surface hydrodynamic scouring test equipment of the solidified soil,the test method of the surface of the solidified soil was for-mulated,and the experimental research was carried out on the solidified soil of the new silt dam.[Find-ings]The results show that the surface of solidified loess with 10%of new type solidifying agent can with-stand the erosion of 30 m/s current,which proves that the new type silt dam has better anti-erosion abil-ity.[Conclusions]Experimental research shows that the anti-erosion characteristics of the surface of hardened soil can be judged by the starting velocity of erosion,the erosion rate at a certain velocity and the surface erosion intensity,which can be used as the evaluation standard of the anti-erosion properties of hardened soil.
