Based on the simulation results, the processparameters of construction technology and construction of storage pipeline is proposed andcalculate the storage pipe cost, the pipe prices and earthwork costs account for a largeproportion. are introduced and influence laws of variousimportant parameters on result are obtained. According to the equivalent methods ofsteel, the equivalent slab thickness and equivalent steel concept are put forward andequivalent formula is used to simplify models, which slab dimension, mesh element,boundary condition and load model etc.
UNDERPASS STORAGE SOFTWARE
On this basis, considering the influenceof pavement structure weight, vehicle load and pipe weight, ABAQUS finite elementsimulation software is used to research on the storage pipe.In order to improve the accuracy of simulation results, it uses the vehicles load tosimulate the traffic load and acquir the load mode. Therefore, it isnecessary to systematically study a more complete underpass drainage system, which hasimportant theoretical and practical significance based on the shortcomings in the presentstudy.This paper, based on the current underpass drainage system home and abroad, takesexample by existing research methods of wet well and storage unit and puts forward thecalculation method of the underpass drainage system. Nowadays, many underpass drainage systemare studied abroad, but they have limitation and don’t conform to China. The perfect underpass drainage systemcan greatly improve the ability of underpass to deal with short-time rainstorm, ensure the roadtraffic not affected by the rainstorm, protect the safety of people’s life and property, prolongthe service life of roads, save the construction funds and have great development prospect,but the underpass drainage system presents a slow development because of shorting ofpeople’s attention and the high investment cost. At present, there are many drainage problems for underpass bridge when storm happens.Thus, as the rapidly developing application demand of highway transportation, the underpassdrainage system must be repaired or reconstructed.
