- 摘要:
- 西安地裂缝是一种地区性的地质灾害，地裂缝的存在给西安地铁的设计和施工等带来一系列的难题和挑战。本文针对西安地铁1号线与F6地裂缝的交叉进行了支护结构设计的探讨分析，调查了F6地裂缝的活动规律和特点。在此基础上，建立了三维有限元计算模型，确定模型的加载方式，分析研究了地铁隧道在施工、支护阶段以及设计年限内最终沉降的结构受力与变形，从而确定了结构设计的方式以及布置形式。同时探讨了支护结构构造，给出了变形缝处结构协调地裂缝活动措施和方法，以期本研究对西安地裂缝带的地铁建设有一定参考。
- Abstract:
- The ground fissure in Xi’an city is a regional geological disaster. The existence of ground fissures brings a series of problems and challenges to design and construction of Xi’an metro. The paper investigates the design of support structure of metro line1 through the ground fissure F6. The mechanics and characteristic of the ground fissure F6 are investigated. A three dimensional numerical model is established. The loading modes are determined. The stress and deformation of support structure are analyzed during the phases of design, construction and usage. According to numerical analysis, the mode and layout of support structure are proposed.
