【摘要】：近年來，隨著國家加大開發(fā)西部的力度，新疆的經(jīng)濟水平迅速提升，公路建設(shè)逐步由平原區(qū)向偏遠(yuǎn)山區(qū)發(fā)展，在設(shè)計、施工工程中不可避免的會遇到高填、深挖路基，因此邊坡的穩(wěn)定性分析以及處理方法對公路建設(shè)與運營的影響也愈發(fā)突出。 工程中常用安全系數(shù)（F）評價路基邊坡的穩(wěn)定性，該指標(biāo)雖能對邊坡穩(wěn)定性進行定量評價，但尚不能對路基邊坡的穩(wěn)定性進行全面描述，因此需要建立一套成熟的、更加符合工程實際的邊坡穩(wěn)定性分析方法。本文通過現(xiàn)場實際調(diào)查，確定邊坡影響因素；同時將可靠度原理與邊坡穩(wěn)定性分析相結(jié)合，充分考慮邊坡影響因素的作用，得出更加貼近實際的邊坡穩(wěn)定性分析方法，此方法能夠直觀、有效的對邊坡的穩(wěn)定性進行細(xì)化判別，同時，依據(jù)細(xì)化判別結(jié)果，結(jié)合相關(guān)軟件分析，制定最經(jīng)濟、有效的邊坡加固措施。 本文以G314線奧依塔格-布倫口段K1602+540～K1602+720處高邊坡為分析對象，選取其中典型斷面作為分析斷面，采用可靠度原理對此高邊坡穩(wěn)定性進行分析，，依據(jù)分析結(jié)果采取相應(yīng)的加固措施，并采用分析軟件對邊坡的加固措施進行研究，分析加固前后邊坡穩(wěn)定性的變化，得出一套更加貼近實際的高邊坡可靠性評價方法及處治措施，為今后新疆地區(qū)的高邊坡提供了一種更為準(zhǔn)確、有效的分析及處治方法。
[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.
