Abstract Research purposes :As the construction technology，technique，equipment and materials for the high - speed railway are becoming more and more advanced，the high quality design，construction and operation are required for the high - speed railway. The fine adjustment of the catenary of high - speed railway is essential to the completion inspection of the high - speed railway，but there is no the relative subitems of the fine adjustment of the catenary of high - speed railway in the current railway engineering electrification quota. Therefore，it is necessary to do the research and work out the fine adjustment quota of the catenary of the high - speed railway in order to reasonably Determine and control the construction cost.
Research conclusions: The quota subitems of the static fine adjustment and dynamic fine adjustment of the catenary of high - speed railway should be set up separately，and the subitems of the dynamic fine adjustment should include the those for the speeds of 250 km/h， 300 km/h and 350 km/h respectively. Under the condition of the reasonable construction organization，the consumptions of the labor s and materials for the static fine adjustment and dynamic fine adjustment should be determined and the comprehensive production should be estimated. The final base price of the static fine adjustment is 3 350. 58 yuan for one catenary per kilometer and the base prices of the dynamic fine adjustments are 4 427. 13 yuan，5 060.29 yuan and 6 481. 25 yuan respectively for one catenary per kilometer for the speeds of 250 km/h，300 km/h and 350 km/h.
