一、裂土路堤坍滑的破坏机理路堤坍滑是指路堤边坡的高度及坡度与土体现有强度所能维持的坡高和坡度不相适应,从而使边坡土体沿着某一强度薄弱面所产生的破坏现象,坍滑的范围一般在气候影响带以内,坍滑的原因主要是土质强度与外营力相互作用的结果。作为路堤填料的裂土,由于含有较多的强吸水性粘土矿物,如蒙脱石、伊利石等,具有
First, the failure mechanism of loess embankment slump Slide embankment slump refers to the embankment slope height and slope with the existing strength of the soil can maintain the slope height and slope do not meet, so that the slope of the soil along a certain strength The damage caused by the weak surface, the scope of slump is generally within the climate impact zone, the main reason for slump is the result of the interaction between soil strength and external power. As the embankment filler cracking, due to contain more strongly absorbent clay minerals, such as montmorillonite, illite, etc., with
