On The Cause And The Normative Circumvention Of The Engineering Risk

The complexity of the natural and social environment of the engineering and the complexity of the engineering itself makes the risk of the engineering. Cause of failure of the engineering practice usually goes to the people's lacking of risk thinking and lacking of perfect risk circumvention. Making study about the engineering risk helps to deepen the understanding about engineering and helps to hence the circumvention of the engineering risk.The engineering risk refers to the concourse of the uncertainty influence the target. The engineering risk includes the political factor, economy factor, natural factor and technical factor that influence the target of the engineering. There are distinguishes between science risk and technology risk. Its means does not limit to the bad, it includes the good that brings about chance.By the reality and constructive of the engineering risk, the cause of the engineering risk includes the nature factor, technology factor, politic factor, economic factor in the engineering activity and the cognition of the engineering risk, the judgment of the engineering's subject and the object, the engineering subject's engineering thinking, and the method of the project risk management.During the access of the engineering risk evolution, no single factor of risk maintains determination unvaryingly, and they influence the accomplishment of the engineering target by acting with each other through nonlinear and fluctuation.The avoidance mechanism of the engineering risk contains the mechanism of economic, law, management, ethic and so on, the ethic mechanism is especially important as a makeup, moreover, for the sick ability of the engineering professional ethics, the ethic mechanism that avoiding the engineering risk should synthesize kinds of ethical principles, establish a kind of ethics encompassing the engineer individuals, the engineering community and the whole society to cope with the engineering risk. The Hangzhou bay bridge has set a good example to show the reinforcement of the ethical circumvention to the economy, law and management circumvention to help the successful accomplishment of the engineering.
