Abstract
In order to study the pore water pressure of saturated muck soil under traffic loading of low frequency in Pearl River Delta, the influence of loading frequency, cyclic stress and consolidation on pore water pressure are analyzed. The results show that the final pore water pressure is increased as the frequency decreases, but the increasing rate of pore water pressure is periodical. Moreover, isotropic consolidation can improve the effective stress of soil and slow down the development of pore water pressure, but it is not the key factor. The key factor of influencing the pore water pressure is the cyclic stress, the following is loading frequency, and the consolidation is the last one. In the end, considering cyclic stress, loading frequency and consolidation, a model of pore water pressure based on a math model is built up.
