【摘要】 在水利水电、公路等工程建设中常常会遇到土坡稳定性问题。由于问题的复杂性，目前能够提供一套比较完善的、具有友好操作界面的计算系统，同时对若干常见的稳定计算方法作对比分析的论文却不多见。问题之二是用传统的确定性方法难以反映加筋土坡稳定随机性变化因素的影响。因此，本文针对上述问题展开了探讨和分析，具有一定的实际意义。 全文共分5章。第1章总结了土坡稳定性问题研究的意义，综述了国内外常用方法的研究动态，提出论文研究的主要内容及技术路线。第2章较为系统地归纳总结了若干常见的极限平衡法，其中，部分计算方法进行了有益的改进。论文介绍了采用Visual Basic6.0语言编制的应用程序，成功实现与AutoCAD链接，自动绘制计算结果图，具有良好的可视性。第3章选择部分实际工程作为考题，检验了第2章介绍的程序；通过分析计算结果，对比某些文献研究的观点，提出了自己的看法。第4章结合“瑞典圆弧法”建立了加筋土坡稳定可靠性分析的极限状态方程，运用蒙特卡洛法，编制了相应的计算程序。通过工程实例，对加筋土坡的定值分析与可靠性分析进行了比较，并探讨了影响加筋土坡可靠性分析的因素及其规律。第5章对全文的工作进行了总结，并指出了有待进一步深入研究的问题。更多还原

【Abstract】 The soil slope stability issues are always discussed in the constructions of hydraulic and hydroelectric engineering & highway engineering and etc. Concerning the complexities of these issues, there’re relatively few dissertations with a more complete and friendly-interfaced calculation system discussed. Furthermore, the traditional definite analysis method can hardly reflect the influence of the random factors of reinforced soil slopes. Therefore, this dissertation has made a tentative research and analysis on the issues mentioned above, which consequently yields certain practical meaning.The whole dissertation consists of five chapters, and the chief substances of each chapter are shown as follows.Chapter 1, summarizing the research significances on soil slope stability issues, provides comprehensive review on the recent development of both domestic & international research works. Then it points out the main contents and techniques of the dissertation.Chapter 2, introducing several kinds of Limited Equilibrium Method in a systematic way, gives some improvement calculation ways. Attains a visual research program in Visual Basic 6.0 that can catenate AutoCAD successfully and draw the result pictures automatically.Chapter 3, selecting certain practical-projects as testing objects, proves the program introduced in Chapter 2. By analyzing the calculating results, comparing with other literature views, puts forward some other corresponding ideas.Chapter 4, Using "Sweden Circular Method", presents a limit state equation on reliability analysis of the reinforced soil slopes stability. Through Monte Carlo Method, a corresponding calculation program is worked out. By the practical projects, the comparison of definite analysis against reliability analysis of reinforced soil slopes is discussed, together with the regularity and the effect of factors on its reliability analysis.Chapter 5, summarizes the research of the dissertation and lists some topics and problems that need studying further more.更多还原
