Application of Underpinning Compaction on Rectification and Reinforcement of Buildings

Taking an engineering project in a certain place of South Jiangsu as an example,the paper explains an effective method suitable for the rectification and reinforcement of buildings in this region:underpinning of anchored and jacked pile excavation and dewatering compaction.Compared with the traditional single reinforcing method,this method is characterized by perfect reinforcement effectiveness,simple and convenient operation without pollution.So,it is especially suitable to the rectification and reinforcement of buildings laid in soft beds with poor loading capacity and high thixotropy.
