黄河三角洲土体非均匀性及对底坡微地貌形成影响

THE INHOMOGENEITY OF SOIL MASS ON THE YELLOW RIVER DELTA AND ITS EFFECT ON THE FORMATION OF SLOPE MICROMORPHOLOGY

通过在潮滩现场 2 0m× 2 0m范围对土体细致的微贯试验和所取样品室内土体粒度分析 ,指出黄河三角洲土体的物理及工程力学性质在小尺度空间上具有非均匀性 ,这种非均匀性对黄河口底坡微地貌形成会产生控制性的影响作用。

An in-site micro-penetration test on the tidal flat(20m×20m) and laboratory granulometric analysis indicate that physical and engineering-mechanical properties of soil on the Yellow River Delta are inhomogeneous in small-scale space. The inhomogeneous properties have an important effect on the formation of slope micromorphology on the Yellow River Delta.
