Aggregate box outsourcing crushing room design, can effectively prevent the leakage of crushing crushing the best shear angle, small resistance, not easy clamping, improves the cutting efficiency;

But the viscosity and viscoelasticity of ultra high molecular weight polyacrylamide decrease significantly. The ability of establishing flow resistance of polyacrylamide is limited after shearing.

The interrelated model of the shear wave velocity with the normal value of ultimate lateral resistance(qsik)and ultimate end bearing resistance(qpk)of the soil around the pile is established.
