| 摘 要： | 根据地铁车站轨道结构的特点,利用集总参数法建立了轮轨竖向耦合振动模型;分析了新建地铁车站深基坑开挖过程中既有车站内的轮轨接触荷载对车站结构及其周围土层变形的影响.通过计算分析认为,列车荷载引起的结构变形在允许值的7 %范围以内,引起的地面沉降在允许值的3 %范围以内. |
| 关 键 词： | 地下铁道 轮轨接触荷载 基坑 变形 |

| Abstract: | Based on the characteristic of subway track structure, vertical wheel/track coupled dynamic model is established by lumped parameters method. The structure deformation of old metro station and ground settlement in proximity by vehicle contact load is analyzed during the deep excavation of nearby new transfer metro station. From calculation analysis, the structure deformation caused by vehicle load is within 7 percent of allowable value, and the ground settlement is within 3 percent. |
| Keywords: | subway wheel/track contact load foundation pit deformation |
