Gradual increases in loading will only cause the water within the soil to flow  out, equalizing the pore water pressure.

负荷的逐渐增加只会导致土壤中的流出，平衡孔隙压力。

A membrane with pores bigger than water particles, but smaller than salt particles, only lets fresh water pass through, transforming what was once undrinkable into a life saver.

一种孔隙大于颗但小于盐颗的膜，只允许淡通过，将曾经不可饮用的东西变救生员。

And as it rains, the water seeps into the soil, the pores become filled with water, and as it keeps raining, the water pressure in the pores increases, which decreases the friction between the grains.

当下雨， 入土壤中，孔隙中充满了，随着下雨的持续， 孔隙中的压增加，从而减少了颗之间的摩擦力。
