【摘要】：近年来,随着我国社会经济和城乡一体化的快速发展,城市的规模越来越大,居民收入不断提高,私家车数量也快速增长,居民活动的范围和对出行的需求也越来越强烈,城市的交通拥堵成为了各大城市的通病,加之内外需增长乏力,房地产发展受限,加大对城市的交通基础设施建设成为稳定经济的首选,导致国内越来越多的城际快铁、高速公路等大型建设项目的出现,隧道则是这些项目中不可缺少的组成部分。隧道工程项目往往投资大、建设周期长、社会影响力强,施工复杂,存在许多风险。如果不进行风险管理,一旦出现质量缺陷或倒塌报废等事故,会给国家和人民带来重大的生命和经济损失。本文综述了风险管理的定义、特点、分类、管理内容及方法,介绍了金竹湾隧道项目概况、设计标准、地形地貌、地层岩性、气候等水文地质条件,并按照风险管理理论对该项目进行风险识别和分类,根据分析识别出其潜在的施工风险。本文首先介绍了隧道施工项目风险管理的发展历史和国内外风险管理研究现状,然后介绍了风险管理的相关理论及方法。并按照风险识别、风险估计、风险评价、风险管理的步骤,对金竹湾隧道的施工风险管理进行实例研究。重点研究了金竹湾隧道的线路概况、设计标准和所处地理位置的水文地质情况,通过风险识别指出金竹湾隧道的13大风险因素,基于此建立了风险系统结构表。随后用层次分析法对风险因素进行了权重分析并排序。采用模糊综合评价确定了该工程的风险程度。最后,对这些风险因素提出了风险应对的办法。
[Abstract]:In recent years, with the rapid development of social economy and urban-rural integration in China, the scale of the city is becoming larger and larger, the income of residents is increasing, and the number of private cars is also growing rapidly. The scope of residents' activities and the demand for travel are becoming more and more intense. Traffic congestion has become a common problem in major cities, coupled with the lack of internal and external growth, real estate development is limited. Increasing the construction of urban transport infrastructure has become the first choice to stabilize the economy, leading to the emergence of more and more large construction projects, such as inter-city fast rail, highway and so on. Tunnel is an indispensable part of these projects. Tunnel projects often have a large investment, long construction period, strong social influence, complex construction, and there are many risks. Once there are quality defects or collapsing and scrapping accidents, it will bring great loss of life and economy to the country and people. This paper summarizes the definition, characteristics, classification, management contents and methods of risk management. This paper introduces the general situation, design standards, topography, lithology, climate and other hydrogeological conditions of the Jinzhu Bay tunnel project, and carries out risk identification and classification according to the risk management theory. Based on the analysis, the potential construction risk is identified. Firstly, this paper introduces the development history of tunnel construction project risk management and the current situation of risk management research at home and abroad. Then it introduces the relevant theories and methods of risk management, and according to the risk identification, risk estimation, risk evaluation, risk management steps. This paper studies the construction risk management of Jinzhu Bay tunnel with the emphasis on the route survey design standard and hydrogeological situation of its geographical location. The 13 risk factors of Jinzhu Bay Tunnel are pointed out by risk identification. Based on this, the risk system structure table is established, and then the weight of risk factors is analyzed and sorted by AHP. The risk degree of the project is determined by fuzzy comprehensive evaluation. Finally. To these risk factors put forward the way to deal with the risk.
