【摘要】 塔里木河下游河道长期断流,生态环境恶化,必须实施河道疏浚工程,从根本上改善塔里木河下游的生态环境。掌握塔里木河下游河道的水文地质和工程地质特征是实施河道疏浚工程的关键,是沿线生态闸堰设置及两岸提防工程修建的基础。通过区域地质特性、水文地质条件、工程地质特征几个方面的研究,得出河道疏浚段的地层岩性、地下水类型、地下水化学类型等特征,为河道疏浚工程奠定了基础。更多还原

【Abstract】 The downstream of Tarim river was setting off for a long-term and its eco-environment has deteriorated, the dredge engineering must be carried out so as to improve the eco-environment. It is the key for the project to master the characteristics of hydrogeology and engineering geology of the dredging stage of Tarim River, it is the foundation of setting up ecological gate and construct levee revetment. According to several aspects study on characteristics of regional geology and engineering geology as well as hydrogeological condition, the paper summarizes a conclusion of stratum lithology, groundwater and its chemical type and the other characteristics there lay a foundation for the dredging project of the river.更多还原
