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水出，平衡孔隙水压力。

The necessary space is there, however, in many forms.

下水是指渗入到下并所有岩石孔隙填满的水。到现在为止，大气水是最丰富的下水资源，是下水在水循环中的一个环节。普通的大气水会从表、降水以及湖侵入到下。在再次冒出表之前，这些下水有时会长时间留在下。最初让人觉得难以置信的是，在我们脚下“坚实的”土中竟然有足够的空间能储存这么些水。

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.

一种孔隙大于水颗粒但小于盐颗粒的膜，只允许淡水通过，曾经不可饮用的东西变成救生员。

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.

当下雨时， 水渗入土壤中，孔隙中充满了水，随着下雨的持续， 孔隙中的水压增加，从而减少了颗粒之间的摩擦力。
