Research on Life Cycle Cost Model of Drainpipe Network Guizhen Hao a, Limin Wangb and Shuna Wangc Hebei Institute of Architecture & Civil Engineering, Zhang jiakou, Hebei,075024,China ahaoguizhen8@163.com, bwlmfirst@sina.com, c wangshunawsn@163.com Keywords: drainpipe network, life cycle, cost model, optimal design, unit cost function of drainpipe network.
In cost model (1), construction cost of network is related to pipe diameter , buried depth and pipe length,when plane arrangement was established,that’s every pipe length is known,so the optimal pipe diameter and buried depth in design were choosed which must consider the economic conditions, right now, construction cost of network is function of pipe diameter and buried depth,that is: (4) Where W1 is construction cost of network,di is pipe diameter of design section,hi is buried depth of design section.The unit-cost function of section is: (5) According toengineering investment estimation index>(The fourth volume of drainage engineering HGZ47-104-2007), the following call [6],the cost of different buried depth and pipe diameter can be found out,
According to the data of engineering investment estimation index>, the function of drainage pipe unit-cost, pipe diameter and buried depth was build up,thus we can estimate life cycle cost of drainpipe network accurately,thereby provide scientific policy-making for choosing the best design of drainpipe network..
