某电力盾构隧道下穿地铁区间施工引起的轨道结构变形及动力特性研究
|
摘要
摘要：随着城市轨道交通的快速发展和建设,大城市地铁已经逐渐形成网格化。一些新建地铁线路和市政管线不可避免与既有线路产生交叉,这些新建隧道在下穿既有线施工时会引起既有地铁结构和轨道的变形,进而影响地铁运营。因此系统化研究下穿工程引起的既有结构变形规律和轨道动力响应对实际工程有很好的参考意义。
本文在查阅大量文献基础上,以某电力盾构隧道下穿地铁复合衬砌区间结构为主要研究对象,从系统的观念出发,综合考虑车体、轨道和结构相互作用,对其动力特性进行研究。本文主要开展的工作如下：
1.根据国内外穿越工程的研究现状和方法,结合目前市政管线和北京轨道交通网的频繁交叉问题提出了：本文主要的研究内容及方法。
2.以实际工程为依托,整理分析实际工程中的监测数据,并总结分析隧道下穿地铁复合衬砌结构时地铁结构的变形规律。
3.应用ABAQUS有限元软件建立车辆—轨道—结构耦合动力学模型,将穿越过程按照相对位置关系划分为6个典型阶段,结合现场实测数据分析不同施工阶段对车辆和轨道结构动力特性的影响。
4.将施工后地铁结构最终变形按比例因子不断扩大,预测不同比例因子变形条件下的车辆和轨道结构动力响应。
ABSTRACT:With the fast development and construction of the urban rail transit, the subway in big cities has shown the trend of gridding gradually. Some of the newly constructed metro lines will cross the municipal pipelines and existing lines inevitably. Thus the deformation of the existing lines and track structures will influence the normal operation when these newly built tunnels traverse under the existing lines. So it is of important reference significance to carry out systematic research of the deformation law of the existing lines and the dynamic response of track structure due to the undercrossing engineering.
Based on widely literature review, this thesis takes a certain electric power shiel tunnel undercrossing the subway structure of compound lining section. Started from system point of view, the dynamic characteristic of the system is studied, considering the interaction of the vehicle, the track and structure. The following subjects are mainly discussed in the thesis:
1. According to the situation and method of present research of the crossing engineering home and abroad, the research content and the study method is proposed with the issues of urban rail transit frequently crossing with the municipal pipelines.
2. Relying on the practical engineering, the monitoring data of the engineering is sorted and analyzed. Then the deformation law of the track structure is concluded when the tunnel undercrossing the subway structure of compound lining.
3. With the finite element software ABAQUS, a vehicle-track-structure dynamic coupling model is established. The crossing process is then divided into six typical stage according to the relative position. With the field test data, the dynamic characteristic of the vehicle and track structure is studies of the every construction stage.
4. By expanding the scale factor of the final deformation of the metro track structure after the tunnel is constructed, the dynamic characteristic of the vehicle and track structure is predicted with the different scale factor.
