【摘要】 河床地质条件复杂,对水工建筑物的刚度、强度、稳定性和工程造价都有重要的影响。因此对河床的地基处理尤为重要,这不仅仅牵扯到经济问题,更关系到广大人民的生命财产安全。水泥粉喷桩广泛应用于河床的地基处理中,它不仅效果好,而且更经济,有利于水利工程的建设发展。河床的地质条件对水泥粉喷桩的施工有着重要的影响,本文先介绍了水泥粉喷桩的基本情况,然后分析了淮水水北调工程瓦子口闸和曲仙河闸河床的地质条件。通过沉降计算和有限元数值分析,对该工程中应用水泥粉喷桩的可行性进行了研究。在通过现场试验检测,对水泥粉喷桩是否满足工程要求做出了检验。现场试验及检测结果表明,河床的地质条件的差异,对水泥粉喷桩的质量有着重要的影响。如今国家对水利工程加大建设力度,尤其是河流上的水闸和泵站等水利工程。水泥粉喷桩有造价低、施工方便和对地基处理的效果好等优点,对水利工程的建设发展和国家的民生建设都有着重大的意义。更多还原

【Abstract】 Riverbed geological complexity, rigidity of the hydraulic structure, strength, stability and engineering costs have a major impact. Ground handling of riverbed therefore particularly important, not only involves economic issues, more related to the lives and property of the people. Widely used in cement Pile Foundation Treatment Project in bed, it is not only effective, but also more economical, beneficial to the development of water conservancy construction.Geological conditions of the construction of cement bed DJM has an important influence, this paper first introduces the basic situation of cement DJM, and then analyzed the geological conditions tile bead gate and song Sin River Gate riverbed. By settling calculations and finite element method analysis, feasibility analysis Cement Pile in the project. By field experiments testing cement DJM meets the requirements of the project to make a test. The test results of the mixing amount of cement, the intensity of the voltage and current strength of the cement DJM construction has important implications; but the geological conditions of the riverbed, the quality of the cement DJM meets the engineering requirements are more important.Today the state to increase efforts in building water conservancy projects, especially sluices and pumping stations and other water conservancy project on the river. DJM has low cost of cement, construction and the effects of cheap and good foundation treatment, construction and development and the livelihood of nation-building water conservancy projects have a great significance.更多还原
