摘要：As a public infrastructure for integrated construction, the integrated pipe corri-dor can extend the service life of the road and save the urban ground space [1]. Rational distribution of integrated pipe corridors provides a strong guarantee for the sustainable development of the city [2]. In recent years, the integrated management of the corridor government and social capital cooperation (PPP) has been widely used in China, in the integrated pipe gallery PPP project, high-speed under the development situation, problems such as out-of-control design in the early stage and loss of trust during the construction period are frequent. Contractual disputes caused by these problems, government repurchase, project suspension and other risks damage the project benefits, which seriously violate the original intention of the project [3]. PPP projects are characterised by long-term, variability and complexity. Risks are more difficult to control than conventional projects. It is a need for a dynamic risk management system that can effectively prevent and control the occurrence of risks, accurately assess risk factors and ensure the protection of risk management.
