【摘要】 我国水资源的分布特点、开发利用状况、经济社会发展和环境的特点，决定了在节约用水的前提下，还需要进行适当的丰贫调剂。为此提出南水北调的设想，其中穿黄隧洞一直是制约南水北调东线的关键因素之一。东线穿黄隧洞在山东省东平、东阿两县境内，位于黄河以下约70m，穿越12个断层。黄河水、孔隙水、岩溶裂隙水“三水相通”是其独特的水文地质特征。通过对南水北调东线穿黄隧洞的前期水文、地质资料、探洞独特的予注浆堵水技术、设计资料等进行分析研究，论证穿黄隧洞设计方案的合理性，确保隧洞在施工期、运行期和检修期的安全性。本文在平洞和斜井段分别选取三个处于不同岩层的典型断面进行分析研究。对穿黄隧洞在各种荷载组合下的应力与稳定性进行研究，解决了穿黄隧洞的支护问题。该项目的研究对于类似的隧洞引水工程，尤其是以隧洞形式过江、过河的工程具有重要的指导和借鉴意义。更多还原

【Abstract】 According to the distribution characteristics and development status of waterresources and demands of socio-economic development and environmentfeatures, the appropriate balance of rich water and dry period is needed on thepremise of water saving. So the assumption of South-to-North Water Diversionhas been presented. Yellow River Crossing Tunnel is one of the key restraints toSouth to North Water Diversion Project East route , which is located in Dongpingand Dong’e counties, Shandong province，about 70m beneath the Yellow Riverbed and crossing 12 faults. The unique hydro-geologic feature of this project isthe interconnection of river water, pore water and karst water.The reasonability of the design alternative of Yellow River Crossing Tunnelis demonstrated based on the analysis of prophase hydrologic data, geologicalmaterials and design data so as to guarantee the project safety during construction,operation and reconditioning periods. Three typical cross sections in differentrock layers are selected at both adit and inclined shaft, and the analysis has beencarried out. In this analysis, the stress and stability under varies loading caseshave been conducted and the corresponding supporting problem has been solved.The analysis of this project can be used for guidance and reference to the familiardiversion project, especially to the project which adopts the crossing tunnelunderneath the river.更多还原
