Abstract

Abstract

The main destruction forms of granular-pile composite foundation is destruction of bulging,and bulging damage is mainly due to the inadequate maintenance of the shallow soil between piles,and the bearing capacity of the soil between piles itself depends also on the mechanical properties of shallow part of soil between piles.Based on the above principle,the after-work shallow reinforcement optimization technology of granular pile composite foundation that stabilized the site of shallow soil between piles to greatly improve the bearing capacity of the composite foundation was offered and the load-bearing characteristics changes of the foundation after and before the reinforcement were compared and analyzed,and the influences of different reinforcement depth on the bearing capacity were demonstrated.Through practical project,it is proved shallow reinforcement technology is reasonable and effective.The conclusion is:that as long as shallow depth of 0.5 ～ 1.0 times granular pile diameter would be reinforced,it could greatly improve the bearing capacity of granular-pile composite foundation.
