摘要
在工程建设之前,相关的技术人员需要对现场的实际情况进行进一步调查,了解施工段的地形地貌特点,对可能发生的地质灾害问题,提出适宜的解决对策,从根源上降低地质灾害问题发生的概率和带来的不利影响。目前,常见的地质灾害治理技术形式较多,但单独针对边坡开展的防治措施仍存在技术的不足,本文中笔者将根据多年的工作实践经验,并结合实例,分析云南大理边坡治理方案比选的影响因素。运用层次分析法确定影响边坡稳定性的安全评价指标的权重系数,在此基础上优化比选云南大理某中学边坡治理方案。通过层次分析法从安全、技术、环境、经济以及其他五个方面确定最优方案为“预应力锚索桩板墙+人字形格构护坡+格构间植草+地表截、排水”,其稳定性均满足工程要求。
Before project construction,relevant technicians need to further investigate the actual situation of the site,understand the topographic and geomorphic characteristics of the construction section,propose appropriate solutions to possible geological disasters,and reduce the probability of disasters and adverse effects from the root.At present,there are many common forms of quality disaster control technology,but there are still technical deficiencies in the prevention and control measures carried out separately for slopes.The author will analyze the influencing factors of the comparison and selection of slope control schemes in Dali,Yunnan,based on years of practical experience and examples.The weight coefficient of the safety evaluation index affecting the slope stability is determined by using the analytic hierarchy process,and on this basis,the slope treatment scheme of a middle school in Dali,Yunnan is optimized.Through the analytic hierarchy process(AHP),the optimal scheme is determined from safety,technology,environment,economy and other five aspects as"prestressed anchor cable pile sheet wall+herringbone lattice slope protection+grass planting between lattice structures+surface interception and drainage",and its stability meets the engineering requirements.
