Abstract：The mechanism of rupture or so-called water films in saturated sand is analyzed. It is shown that there will be no stable water films in the saturated sand if there exists no effective stress. Only when the seepage velocity always equals to zero，do there exist stable water films. The evolution of water films is compared with some experimental results.
