喀斯特不同岩性发育区自然土壤力学特征研究

摘要

This paper studied different development on natural soil compactness, angle of internal friction and cohesion in Karst area.The result showed that carbonate formation of natural soil compactness is higher and the soil corrosion resistance is strong.The natural soil compactness is the lowest in the limestone which is vulnerable to erosion.The corrosion resistance of the natural soil formed in the pure carbonate area is higher than that in the muddy carbonate area.The pure carbonate rock area of soil slope is not prone to collapse.%对喀斯特不同岩性发育区自然土壤的紧实度、内摩擦角和黏聚力进行了研究,结果表明:碳酸盐岩发育形成的自然土壤紧实度较高,土壤抗蚀性较强,其中自然土壤紧实度以泥灰岩最低,较容易受到侵蚀;纯碳酸盐岩区发育形成的自然土壤的抗蚀性要高于泥质碳酸盐岩区,纯碳酸盐岩区发育的土壤坡面不容易发生崩塌.
