The Engineering Properties Discussion of Dredger Fill Through the Cone Penetration Test

Effecting by the action of gravity hydrodynamic force and improving through the vacuum consolidition way, the dredger fill of Tianjin Binhai New Area has more complex engineering properties. Through the cone penetration test(CPT) and other way, it can be divided into Hard shell soil, Weak Clay soil and Sand soil, All together, three strata from top to bottom. The Hard shell soil on the top and sandy soil in the bottom consist high intensity, unsteadable distribution characters. Just as the soft soil, low intensity and high compressibility is the main characters of Weak Clay soil. The Dredger fill near the Water outlet, which is mainly composed by Weak Clay soil, has poor engineering properties.
