中文摘要：

地实验在人工的降雨下面被进行在斜坡上调查土壤失败的过程。失败时间地不连续、空间地分离，这被发现，与大量大小，由土壤潮湿和毛孔水压力的变化伴随了。明确地，实验显示土壤失败是更可能的与好粒子的高内容发生在斜坡上；毛孔压力响应土壤失败变化因为失败显然影响内在的土壤的毛孔。好粒子从的移植对斜坡的更低的部分上面也在斜坡侧面影响毛孔水压力变化。土壤异质在毛孔水压力在变化上有重要效果，这被结束，并且好粒子交通影响毛孔水压力，以及集体深度的大楼，起始的孔，它对理解斜坡失败的空间特征关键。

英文摘要：

Field experiments were conducted under artificial rainfalls to investigate the processes of soil failures on slope.It is found that the failures were temporally discontinuous and spatially discrete,with a wide range of magnitudes,accompanied by variations of soil moisture and pore-water pressure.Specifically,the experiments indicate that soil failures are more likely to occur on slope with high content of fine particles;the pore-pressure varies in response to soil failures in that the failures evidently affect the pore of the underlying soil.Migration of fine particles from upper to lower part of the slope also impacts the pore-water pressure variations in the slope profile.It is concluded that soil heterogeneity has a significant effect on variation in pore-water pressure,and fine particles transportation influences the building of pore-water pressure,as well as the mass depth,initial porosity,which is key to understanding the spatial characteristics of slope failures.
