The way to prevent the crack is to reduce the penetration ratio.
减小熔合比是防止裂纹产生的关键。
2
Concrete expansion admixture can compensate concrete shrink-age so that the concrete structure can resist crack and penetration efficient-ly.
掺加适量膨胀剂可补偿混凝土的收缩，使混凝土结构达到较好的裂渗控制效果。

The crack not only weakened the soil structure of the slope, but also provided passage for water penetration, which further led to soil softening and strength decrease.
