【摘要】：多年来隧道施工一直事故频发,不仅导致了严重的经济损失和人员伤亡,而且在社会上也产生了非常恶劣的影响,引起人们对隧道施工安全状况的广泛关注。因隧道施工期间对隧道施工风险的控制极为重要。本文针对复杂地质条件下的胡麻岭隧道施工风险的控制做以下研究:(1)结合依托隧道施工项目的工程实际、现场的施工条件、地质勘察报告、施工图纸、施工组织设计等技术资料,对胡麻岭隧道施工过程中的风险进行了风险辨识,根据项目所需对其中的典型风险进行了选取与评估。(2)采用数值模拟的方法对胡麻岭隧道的几种预定开挖方式进行了比较,在此基础上并对隧道挑高段设计施工方案进行了创新优化。(3)为进一步保证隧道施工的安全进行,对施工风险控制一体化措施进行了研究,提出了富水粉细砂地层隧道防塌防变形控制技术和富水粉细砂地层隧道质量风险控制措施。
[Abstract]:Tunnel construction accidents have been frequent for many years, which not only lead to serious economic losses and casualties, but also have a very bad impact on the society, causing widespread concern about the safety of tunnel construction. It is very important to control the risk of tunnel construction during tunnel construction. In this paper, the following research is done to control the construction risk of Humaling tunnel under complex geological conditions: (1) combining with the engineering practice of the tunnel construction project, the site construction conditions, the geological survey report, the construction drawings, Based on the technical data, such as construction organization design, the risk identification of the risk in the construction process of Huamaling tunnel is carried out. According to the requirements of the project, the typical risks are selected and evaluated. (2) the numerical simulation method is used to compare several predetermined excavation methods of Humaling tunnel. On this basis, the design and construction scheme of the high section of the tunnel is innovatively optimized. (3) in order to further ensure the safety of the tunnel construction, the integrated measures of construction risk control are studied. The control technology of tunnel sloughing and deformation prevention in water-rich silty sand formation and the quality risk control measures of tunnel in water-rich silty sand formation are put forward.
