疏浚机具在土壤切削过程中，由于处土部分与土壤之间的粘附，会使得切削阻力增大，疏浚效率降低。相互接触的两个刀齿界面上存在不同的粘性物质如水、空气、黄油时，会使得界面的粘附力不同，从而导致拉伸所需的拉力大小不同。通过试验，分别对光滑表面刀齿和凹坑形表面结构刀齿，以及两刀齿界面间采用不同的粘性物质，来研究两相互接触的刀齿界面间粘附力大小的影响因素。试验表明：对于相同的刀齿表面，当界面采用空气、水、黄油时，其界面的粘附力依次增大；对于界面间采用相同的粘性物质时，凹坑表面结构刀齿的界面间的粘附力较光滑表面刀齿较小。

During the cutting process of the dredging machines in the soil,because of the soli conglutination,its cutting resistance increases and the dredging efficiency lowers.Because the tangent surface of the tool conglutinates the viscous material of different adhesion force,such as water,air,butter,the tensile force is different.The different viscous material is used to study the influence factor on the anchoring strength between the tool surfaces. Tests show that when the interfaces of the same tool surfaces adhere to the different viscous material, the adhesive power is also different,but the adhesive power of the unsmooth tool surface is lower.
