| 摘 要： | 针对软土地区的桥台 ,采用有限单元法建立桥台 -桩系统分析模型。对软土在桩上由于超载产生的侧向压力进行了参数研究 ,研究表明这种土压力荷载相当大。最后对一实际桥台进行了计算 ,计算结果可以合理地解释该桥台的开裂现象 ,为桥台加固提供理论指导

| Abstract: | For analyzing the abutment-pile system on soft soil using the Finite Element Method, a model is established in this paper. Study on parameters of lateral earth pressure with the model shows that there is considerable earth pressure due to surcharge of embankment. Finally, calculation of an abutment in engineer-ing practice is carried out with results that can explain the cracking of the abutment and provide guid-ance for the reinforcement of the abutment. |
