The Research And Application Of Subway Station Construction Risk Management

The development of subway engineering construction is rapid in China currently, For the subways always go though the downtown areas of city, which have high density of population, complicated and various buildings’foundations, horizontal and vertical crossing intricately pipelines, complex hydrogeology conditions, at the same time, it is lack of ready-made construction experience which can be adopted. All those factors led to frequently accidents during the procurement of the site work, costing huge casualties and properties loss. So how to succeed in subway construction risk management and reducing the consequences and decreasing the probability of occurrence is extremely urgent.This article bases on the domestic and overseas’engineering risk management technology together with the previously achievements which obtained during the research of risk management, makes some optimizing and improving, aims at the character of city subway station, the method statement and personality of subway station construction risk, applies information system technology, kinds of risk analysis and assessment methods, risk surveillance and risk alarm technology etc. to the subway station risk management, which can provide reference and usage for the subway station project construction risk management.This article starts the research from the method statements of subway station construction, each method’s specialty and its suitable scope, then use all kinds of methods to identify, classify and grade the risk. And adopt some definite measurements and instruments to supervise the fateful, unnoticed risk resources elements, synthetically analysis and identify the risk state according to the supervised results, to make a sequence of control measurements such as advanced risk alarm, risk tracking, risk preventing and risk mitigation; Combine all the subway station construction participants with risk management system to make a celerity and high efficiency risk management through the entire procure. At last, raises a point for managing implementation measurements of subway station construction risk management, and takes theory into practice by a case study.
