城市轨道交通工程造价风险评估研究

城市轨道交通工程是一项投资大、建设周期长、社会影响大的大型工程项目，它存在很多风险因素。只有对这些风险因素进行科学的评估和控制，才能确保工程造价不会失控。介绍城市轨道交通工程的造价组成及其特点，在此基础上分析城市轨道交通工程的造价风险，最后从风险识别、风险分析、风险评价三个方面对工程造价进行了风险评估。

Risk Assessment of Urban Rail Traffic Engineering Cost

The urban rail traffic engineering is a large-scale engineering project with high investment, long construction cycle and profound social influence, which has many risk factors. These risk factors must be well estimated and controlled, or the engineering cost will be out of control. This article firstly introduces the cost composition and features of urban rail traffic engineering, then analyzes its cost risks, and finally carries out risk assessment of the engineering cost in three aspects such as risk identification, risk analysis and risk evaluation.
