Research On Construction Progresscontrol Of Long Distance Water Diversion Project

At present our country has some water diversion projects Under Construction，in theprocess of project construction progress problems Appear gradually.Long distance waterdiversion project have some characteristics， cross-regional， large investment， longconstruction period，a lots of construction units and progress influence factors，in constructionprocess，Lagging progress，time delay is often happened. Based on the scientific research andtechnical requirements of the construction，On the basis of the existing research results，thispaper research long distance water diversion project construction process node time delay orprogress influencing factors between the progress，and hopes to provide long distance waterdiversion project progress control with scientific and effective theory guidance.First of all，based on existing research results of progress control field and thecharacteristics of long distance water diversion project itself，this paper analyzes theengineering construction progress control theory system，systematically analyzes someconstruction progress control principle，construction progress comparative method. Second，recognize the construction progress influencing factors，According to the characteristics oflong distance water diversion project，lists main construction progress influencing factors oflong distance water diversion project， and qualitatively analysis on the progresstransmission influence of the single work；On this basis，combining with the NetworkPlanning Technique established a fuzzy network schedule evaluation model，Puts forward adynamic analysis method of key circuits，Analysis of engineering examples with the analysismethod. The third，the defined key line as the foundation，quantitatively research progresstransfer relationship of single work，citing Directed Graph Theory and Risk Unit TransferTheory，established a completion probability analytic model of long distance water diversionproject based on the network plan，fully considered the progress transmission influence of the single work. Finally，with one project of the south-to-north water transfer project as anexample，using the completion probability analytical model，calculates risk degree of theproject completed on time.
