Disposition of the hydraulic structure of sedement foundation;

The application of the method combined with manual hole digging pile and steel pipe pile in quicksand formation;

At present, the most popular trenchless pipeline installation method is guided boring, but in the guided boring cave-in of the borehole wall eternally are encountered in quicksand formation.

According to the characteristics of deep sand foundation, this paper proposed two kinds of seepage prevention schemes, i.

Upon the p ractice of the pit excavation in this project,presents the solution of retaining and underground water control during pit excavation in sand ground near river.

This paper introduces the mechanism of removing the liquefaction of the sandy soil foundation with the vibro replacement stone column, and connecting with the engineering example, makes evaluation on the results of removing the liquefaction of the sandy soil foundation with the vibro replacement stone column, which possesses certain guiding significance for the similar engineering.

In this article,the bearing behavior and load transfer mechanism of piles in sandy soil foundation are discussed on the basis of the static loading test in XiangYin-XiangJiang bridge,the effect of piles length on the transfer of axial force and the action of lateral friction resistance are analyzed by comparison with the same proportion of length to diameter.

The treatment of sandy soil foundation by deep agitation method is not common in engineering practice.
