【摘要】 在顶升纠偏技术中,根据空间桁架理论,托换结构简化为拉一压杆模型。本文用试验的形式对这一方法的适用性进行研究。通过对模型的加载试验,分析承台的受力特征、破坏过程、形态及其极限荷载,来验证用空间桁架理论设计托换结构的合理、安全和经济的特性。为工程实践提供了实践和理论依据。更多还原

【Abstract】 In rectified technique by raising,the underpinned structure will be simplified to the tension-compression bar model.This paper studies the adaptability of the method by tests.Through the loading test to the model,the stressing characteristics,failure process,feature,and the limit load of the bearing platform are analyzed to check the reasonable,safe and economic characteristics of using the space truss theory to design the underpinned structure.This provides the practical and theoretical basis for the performance of the project.更多还原
