| 摘 要： | 当饱和砂土层液化后,可能发生不均匀渗流,导致砂土中断层的形成,从而为滑坡提供了滑动面。对饱和砂土中的断裂(或称作水层)现象进行了分析,结果表明,只有当砂土层中某处被堵塞不能渗流且该状态一直保持时,才有稳定的断层,否则断层会逐渐消失。同时,对分析结果与试验结果进行了对照。

| 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. |
