Like a chopstick, inserted into the soil is not directly on the ground than in a more stable, the pile is equivalent to the chopsticks into the earth part.
Because of the better foundation, the building can be built high, durable and firm...
Because the foundation bearing capacity of the building is low, it can not meet the load requirements of the upper building. Piling is to pass the weight of the building to the soil with high bearing capacity of the foundation. Not all buildings are piling, and if the bearing capacity of the foundation meets the requirements, the pile can not be piled completely. Like Beijing, few piles are used because of the good bearing capacity of the foundations.
