Abstract

The observation results of the bridge head experimental site of Jialichen Bridge are analyzed such as vacuum degree, ground water table, flowrate, pore water pressure and surface settlement.The combined mechanism of vacuum combined with surcharge preloading is discussed.It is not the way of the vacuum loading combined with surcharge loading but the the way of pore water pressure difference caused by vacuum preloading combined with the the pore water pressure difference caused by surcharge loading.The testing results show that soft foundation treated by vacuum combined with surcharge preloading is very effective.
