A Study On "Consortium" Project's Apprasising The Country Economy In Hydraulic Engineering

At the beginning of this thesis according to our country's water resources and hydraulic engineering management condition at present, the author have reconsidered why the problem of distortion and timeliness in appraising the country economy of hydraulic engineering is surviving in our country. Thus educe the research and the discussion about appraising the country economy, put forward many feasible methods and proposal, and has established the synthesis economic evaluation system and the appraisal model. This thesis is based on the sixth special topic "The reasonable water resources disposition in Ningxia economical ecosystem "of the western significant project " Research on the reasonable water resources disposition of Ningxia economical ecosystem", and has carried on the application and the confirmation for the synthesis economic evaluation system and the appraisal model by Ningxia's correlative hydraulic engineering projects. The thesis is a supplement and consummation to the method of national economy appraisal at the present. The main productions in this thesis are as follow:1.Resolved the problem of "exterior effect" among the correlative engineering projects. The first, through citing the concept of "consortium" in "Method And Parameter Of Construction Project's economic evaluation "( Second edition), adopts the method expanding project scope suitably, the author makes national economy evaluation by regarding several correlative projects as a whole, as a big project the big project is also call "consortium". Then the author makes national economy evaluation by using the principle of probability. So we not only can change many exterior effects into interior effects, but also can put them into the cash flow to carries on the overall the quantification analysis to some exterior effects that cannot be changed into interior effects.2.Resolved the problem of quantifying project's ability of resisting risk in the condition that cannot carry on the probability analysis. through adopting a new method and analyzing massive sensitive analysis data, This thesis induces the"uniformity"rule in the uncertainty analysis under the same fluctuation scope condition, Then through the deductive, cites a new variable named fluctuation index of EIRRΦto represent the project's ability of resisting risk.
