Background

The traditional sandy soil liquefaction-resistant foundation treatment is generally carried out by adopting a dynamic compaction method, such as a dynamic compaction or vibroflotation compaction method. However, the dynamic compaction method has certain applicability when reinforcing a sand layer with high fine grain content, such as the vibroflotation compaction method is only applicable to sandy soil foundation with fine grain content (the grain diameter is less than 0.075mm) not more than 15%; the dynamic compaction foundation treatment is suitable for sandy soil foundations with a high fine grain content range (30-40%), but the reinforcement depth is generally not more than 10 m. Therefore, for the easily liquefied sand layer with high fine grain content, a drainage-based anti-liquefaction foundation construction method is often needed, and the ultra-pore water pressure generated under the action of an earthquake is quickly dissipated by providing vertical and horizontal drainage channels.
