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.

Research on bearing capacity test of pier foundation on cohesive soil;

Application of composite element method in sand drain ground finite element analysis;

The consolidation behavior of the sand drain ground during the process of filling the embankment was monitored by the settlement plate, telescoping tube settlement gauge and pore water pressure cell.

Probabilistic analysis method simplied of consolidation for sand drained ground is concluded from sensitivity analysis of the degree of consolidation to uncertain parameters.

Some new problems appear with the increasing popularity of installing vertical drains, therefore, developing more efficient calculation methods to analysis the behavior of sand drained ground plays an important role both in the theoretical and the practical sides of such problems.

Therefore, to develop more efficient calculation methods to analysis the behavior of sand drained ground plays an important role both in the theoretical and the practical sides of such problems.
