With economic development, the increasing scale construction projects, technology becomes more complex, and many of the projects the company to manage multiple projects simultaneously, thus the introduction of program management, which is coordinated simultaneously manage multiple projects with interrelated, to obtain greater than the overall effectiveness of individual projects, the development of the project management is an inevitable trend. In our vast land, mountainous area of ??the total land area of ??65.68%. 1,735 counties in China, more than 48,000 townships, 57% are located in the mountains, we can see the development of mountainous areas affects the pace of the entire national economy. Transportation is a major obstacle affecting mountain development, we must accelerate the mountain transportation construction. Mountainous terrain, bridges and culverts, tunnels, multi-protection works, construction difficult, high cost, the construction process is fraught with uncertainty, how to effectively control risks, reduce losses caused by risk occurring on mountain highway program management is very important. This stand of owners group on mountain highway project risk management. First expounded program risk management theory and then discuss the specific program risk management process: risk identification - Risk analysis and evaluation - Risk coordinated control. Program risk identification of the entire construction process to identify the risks, identify the content includes not only within a single project risks, but also includes project and inter-project, tenders mutual influence between the emergence of new risks. Second, according to MC method to estimate individual risk probability, risk group due to the project is relevant, so you should calculate the correlation coefficients between the main risks and use fuzzy evaluation method to compare levels and for different risk events take appropriate coordinate control measures . Finally, a special mountain road terrain, the limited available resources, there is a lot of space between the cross tenders, focusing on resource conflict risk and schedule risk for discussion. Use of network planning technology, key chains and other knowledge, is proposed based group critical chain project schedule, and apply P3e / c software group schedule for the project to be adjusted to reduce the risk behind schedule. Group of mountain highway project through the establishment of resource allocation model, reasonably determine the precast yard, debris fields and other public land resources to effectively control the risk of conflict. And the use of communication, incentives and other measures to strengthen the organization and management of the project group, reduce project group construction process due to bad organization risks. Group in the project construction process, by comparing the actual owners pay costs and program investment costs, to understand the extent of deviation investment project group on various projects to strengthen change management, coordination and optimization progress. End of the article using the case of a mountain highway in the form of coordinated management of risk has been studied and summarized results of this study and made a note inadequacies. Innovation of this paper lies in the mountainous highway program risk management conducted a comprehensive discussion and proposed a set of coordinated and effective risk control methods.
