| 摘 要： | 桩柱式桥台因软土地基引起桥台位移，并出现了一些病害，桥台位移严重地影响桥梁上部结构的安全。本文通过分析桥台桩基与地基的相互作用，以及软土地基桥台后填土对桩基产生的桩侧土抗力，阐明了由此而引起的桥台位移影响及行之有效的防治措施。 |
| 关 键 词： | 软土地基 桩柱式桥台 附加应力 防治措施 |

| Abstract: | When a pillar-shaped bridge is built in soft soil foundation, bridge abutment displacement and bridge hazards appear possibly at the same time. The stability of bridge upper structure is influenced by bridge abutment displacement severely. In this study, based on an analysis of the cross-action between bridge abutment base and soil founda- tion, and the lateral soil resistance due to the baekfilled soil of bridge back, the causes of the bridge abutment displacement are clarified. Hereby, some feasible treatment measures is also provided. |
