Abstract: In order to improve the management efficiency of intermediate quantities measurement of large hydropower station, on the basis of the on-line measurement verification and signature, combined coding technology was used to establish flexible correlation between measurement information and quality evaluation information. The improved nested set model was adopted to encode the contract bill of quantities, the spanning tree algorithm was used to classify and summarize the total list of quantities. The automation of pre-audit for quality evaluation of measurement objects, and real-time reminding and warning including lag, overrun, duplication for measurement can be realized and ultimately offer support for measurement decision. The system has been applied to the construction management of Lianghekou Hydropower Station and effectively improved the management level of on-site measurement.

Key words: quantity measurement management, quality assessment, combined coding, improved nested set model
