摘要: 对沿江两岸河漫滩的分布特征、漫滩地貌、漫滩结构、漫滩基底结构、漫滩水文地质条件等进行了分析. 同时, 对漫滩地层的物理力学性质, 包括典型的漫滩土层和非典型的漫滩土层, 根据不同出露地点进行了剖析、对比, 从而对长江中下游港口建设的环境工程地质条件从地貌特征、地层特性以及不良地质现象等方面进行了综合评价. 在此基础上, 详细论述了合理利用有利条件和避开、治理不利条件的方法, 为长江中下游港口建设提供了有价值的基础资料.Abstract: The distribution feature of the flood land along the river, its landform and structure, basal structures and hydrologic conditions are analyzed based on the data collected systematically. At the same time, the physical-mechanical properties, including the typical and non-typical flood land soil, are compared according to the difference of the outcrops. The environment engineering geology condition, from the landform feature, stratum structure to unfavorable geology condition, of the harbor construction along the middle and lower reaches of the Yangtze River were evaluated synthetically. On the basis of the study and analysis, the methods of utilizing the good environment condition to keep away from and prevent the unfavorable environment geology condition were advanced, which is valuable for the harbor construction along the middle and lower reaches of the Yangtze River.
