摘　　要：长江出三峡南津关口自宜昌而下 ,由于河谷增宽 ,水力梯度减小 ,沉积物的颗粒由上游至下游逐渐变细、各类土层的工程地质性质也逐次变差。本文以长江中下游河谷两岸漫滩土层的物理力学性质和基本地质环境条件予以工程评价 。The Yangtze River becomes wide after it runs through the Nanjinguan Pass of theThree Gorges, then the hydraulic gradient decreases. The grains of the sediments gradually thindown from the upper reaches to the lower reaches, hence the engineering geological condition becomes bad gradually from the upper to the lower reaches of the river. With expecting to provide data of physical properties, engineering geomechanical characteristics, and basic geologic environment of the floodplain land in the modern beach of the middle and the lower reaches of the river.
