| Abstract: | ?The engineering test is introduced of preventing loess cave collapse dueto infiltration water during the heaviest rainfall in 50 years by using the principle of water tightness of soil-water potential in soil sandwich. And the effectiveness and practicality of water infiltration prevention of two-or three-layer sandwich soil structure indicated in 3-year experimental observation is discussed. |
