【摘要】：近年来，随着国家加大开发西部的力度，新疆的经济水平迅速提升，公路建设逐步由平原区向偏远山区发展，在设计、施工工程中不可避免的会遇到高填、深挖路基，因此边坡的稳定性分析以及处理方法对公路建设与运营的影响也愈发突出。 工程中常用安全系数（F）评价路基边坡的稳定性，该指标虽能对边坡稳定性进行定量评价，但尚不能对路基边坡的稳定性进行全面描述，因此需要建立一套成熟的、更加符合工程实际的边坡稳定性分析方法。本文通过现场实际调查，确定边坡影响因素；同时将可靠度原理与边坡稳定性分析相结合，充分考虑边坡影响因素的作用，得出更加贴近实际的边坡稳定性分析方法，此方法能够直观、有效的对边坡的稳定性进行细化判别，同时，依据细化判别结果，结合相关软件分析，制定最经济、有效的边坡加固措施。 本文以G314线奥依塔格-布伦口段K1602+540～K1602+720处高边坡为分析对象，选取其中典型断面作为分析断面，采用可靠度原理对此高边坡稳定性进行分析，，依据分析结果采取相应的加固措施，并采用分析软件对边坡的加固措施进行研究，分析加固前后边坡稳定性的变化，得出一套更加贴近实际的高边坡可靠性评价方法及处治措施，为今后新疆地区的高边坡提供了一种更为准确、有效的分析及处治方法。
[Abstract]:In recent years, with the national efforts to expand the development of the western region, the economic level of Xinjiang has rapidly improved, and highway construction has gradually developed from plain to remote mountain areas. In design and construction projects, it is inevitable to meet high filling and deep excavation of subgrade. Therefore, slope stability analysis and treatment methods of highway construction and operation of the impact is increasingly prominent. The safety factor (F) is commonly used to evaluate the stability of subgrade slope in engineering. Although this index can quantitatively evaluate the stability of subgrade slope, it can not describe the stability of embankment slope comprehensively, so it is necessary to establish a set of mature. More in line with the actual engineering slope stability analysis method. In this paper, the influence factors of slope are determined through the field investigation, and the reliability principle is combined with the slope stability analysis to fully consider the effect of slope influence factors, and a slope stability analysis method is obtained, which is closer to the actual situation. This method can directly and effectively refine the stability of the slope, at the same time, according to the results of refinement discrimination, combined with the analysis of relevant software, the most economical and effective slope reinforcement measures are formulated. In this paper, the high slope at K1602 540~K1602 720 in Oytag-Brunkou section of G314 line is taken as the analysis object, and the typical section is selected as the analysis section, and the stability of the high slope is analyzed by using the principle of reliability. According to the results of the analysis, the corresponding reinforcement measures are taken, and the reinforcement measures of the slope are studied by using the analysis software, and the changes of the slope stability before and after the reinforcement are analyzed. A set of reliability evaluation methods and treatment measures for high slope are obtained, which provide a more accurate and effective analysis and treatment method for the high slope in Xinjiang.
