excess pore water pressure dissipation

The dissipation of excess pore water pressure has a direct bearing on the design of pile foundation in saturated soft soil.

饱和软土地基中桩基设计与沉桩引起的超孔隙水压力大小及其消散有密切关系。

Loading rate effect, creep and stress relaxation should be attributed to the viscous properties of the sand specimens, but not to the delayed dissipation of excess pore water pressure.

加载速率效应、蠕变以及应力松弛都是砂土材料本身黏性的反映，而与超孔隙水压力的消散无关。

However, the dissipation model of excess pore water pressure after liquefaction is only affected by the confining pressure.

相对密度仅对液化后的本构模型有较大的影响，而对孔压消散模型基本没有影响。
