Anti-sliding piles are fit constructions which used extensively in landslide prevention.Their durability is very important which influences their lives.The extent of the concrete neutralization is an important influencing factor.By a model experiment under acid rain erosion and stress coupling

tested concrete strength and neutralization depth after eroded by acid rain.The results indicate that the concrete strength of anti-slide pile firstly increases and then decreases gradually after acid rain erosion.On stress coupling

concrete neutralization depth of anti-slide pile is very different to that without stress.Concrete neutralization depth under bending tensile stress is larger than without stress

while concrete neutralization depth under bending tensile pressure is smaller than without stress.The stress level has a certain influence on concrete neutralization depth.
