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

With test data,field information and a practical example of sand soil foundation pit under complex geologic conditions,authors introduce the design process of adopting the freezing construction method to treat foundation pit,and provide measures to restrain frost upheaval and to prevent subsidence.

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.

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.

Dynamic centrifuge model test of an unconfined sandy foundation

Based on the treatment practices of sandy soil foundation with vibro-compaction granular piles for the large oil tanks of Maoming Petrochemical Company in Maoming City,Guangdong Provinces,ome problems about the design of vibro-compaction granular piles are discussed.

For the sandy soil foundation with not large drop depth it generally selects to use light well drop, so it can meet the requirement of safety, adaptation and economy.
