Water Conservancy And Hydropower Project Risk Management

Project risk management theory is introduced into China from Europe and theUnited States, after years of research, in the aspect of risk identification and preventionfor out some feasible methods and measures, and gradually formed a risk managementthis emerging discipline. Now has been gradually applied to various fields ofengineering project construction in China.Along with the development of domestic engineering construction project legalperson responsibility system, engineering project bidding system, project legal personresponsibility system owner and step by step of the implementation of the riskinvestment mechanism, water conservancy and hydropower construction projects athome and abroad have made considerable development. Water conservancy andhydropower project with large investment, long construction period, not only thecontractors of various complex relationship, organization, experience, but also has theirresistible factors such as vulnerable to natural disasters and the impact of suddenaccident, has the wind damage accident, risk uncertainty, etc. Therefore, the Chinesegovernment has adopted a series of measures to strengthen the safety production ofconstruction of water conservancy and hydropower industry, hydropower constructionprojects to maintain the stability of the security situation.Study the risks of the construction of hydropower station in China started late,water conservancy and hydropower construction industry generally attaches greatimportance to the investment risk management, and despise safety, schedule, quality andother aspects of risk management. In water resources and hydropower engineeringconstruction process to carry out all-round, the whole process of risk management,control, prevent and eliminate the safety hidden trouble in time, is an urgent andimportant topic.Jinping-I Hydropower Station is located in the qinghai-tibet plateau to the sichuanbasin transition area, construction area is located in the liangshan yi autonomousprefecture, sichuan dam site terrain, severe rock broken, poor construction environment,external traffic, communication is not smooth; Numerous long construction period,construction personnel, in the construction process of construction of high slope, deepcavern excavation of high ground stress, the unloading cranny technical problems brought serious influence to the risk management of hydropower station.In this paper, based on the identification, analysis and evaluation of project riskmanagement, disposal, such as basic theory, fully recognize the hydropower stationconstruction project risk source of the project, list the construction engineering projectrisk list; In the size of the hydropower station construction engineering project risk andits relative importance evaluation; According to the water resources and hydropowerengineering construction project risk control overall goal, according to the control ofrisk factors, risk retention and risk transfer of hazards such as management strategy,choose security risk management to reduce or reduce the project risk.Based on Jinping-I Hydropower Station project as an example, the project riskmanagement, mechanical and electrical installation for Jinping-I Hydropower Stationproject according to the different projects subject to security work breakdown structure,puts forward the Jinping-I Hydropower Station construction of electrical andmechanical equipment installation engineering safety risk management.
