京珠粤境高速公路 K153+150~300 边坡支护设计中文摘要本设计为京珠高速甘塘至翁城段 K153+150～K153+300 边坡进行稳定性分析和加固设计，并且介绍了稳定性分析的方法，Janbu 法和 Bishop（毕肖普）条分法。在稳定性分析中，根据地形选择两个典型的剖面，运用 slope 5.0 软件对该边坡做了相应的分析，每次分析进行全局搜索，搜索出其中最小安全系数对应的滑动面，之后对分析结果进行评价，从而确定出它的最小稳定性安全系数，确定是否进行加固。然后在对它进行加固设计时，综合考虑边坡所处地质条件等多方面因素，最终选用了抗滑桩和锚杆两个不同的加固方案。结合边坡防排水原则，对边坡进行了防排水设计。关键词：边坡；稳定性分析；加固；锚杆；抗滑桩；防排水SLOPE SUPPORT DESIGN OF THE SLOPE AT BEIJING-ZHUHAI EXPRESSWAY FROM K153+150~K153+300ABSTRACTThe design is about reinforcement of slope which locates in Bid I section K153+150～K153+300 of Gantang to wengcheng along Beijing-Zhuhai expressway. The contents of the design include the slope stability analysis and design of strengthening governance and stability on the analysis of the way, Janbu Law and Bishop (Bishop) of the Act. The stability analysis, Selected two typical cross-sectionthe use of software slope 5.0 of the slope to do the corresponding analysis to determine its stability of the minimum safety factor to determine whether reinforcement, overall situation search were performed in order to obtain the sliding surface which with the least safety factor，then evaluation was made to the slope. And then it was reinforced in the design, considering slope where geological conditions, and other factors, the final choice of the anti-slide pile retaining wall and anchor two different reinforcement programme. with slope-drainage principles, the slope of the anti-drainage design.Key words: Slope; Stability Analysis; Reinforcement; Anchor; anti-sliding pile; anti-drainage目 录 1 工程地质情...
