    西南地区高填方机场软基加固处理

    THE REINFORCEMENT FOR THE SOFT GROUND OF HIGH EMBANKMENT AIRPORT IN THE SOUTHWEST OF CHINA

    • 摘要: 多山的西南地区机场工程实践具4个主要特点:1场区地质条件复杂,常分布有软弱土层;2高填方;3高地震烈度;4机场建设周期短。因此,软弱土层的加固处理是机场建设成败的关键,综合西南机场工程实践的具体情况,认为强夯(特别是置换强夯)、碎石桩、换填和碾压是4种经济合理的地基处理方案。文中结合某机场工程,对这4种处理方法的加固机理和方案设计作具体阐述。

       

      Abstract: The complexity geology conditions usually accompanied with maldistributed weak soil, high embankment, intensive earthquake, short construction period are the main characteristics during the airport construction in the southwest of China. Therefore, it is indispensable to reinforce the weak soil. Summing up the airport construction instances in theses region, the rational and economic treatments are dynamic consolidation(especially the replacement dynamic consolidation), compaction gravel pile, cushion and rolling. Then their reinforcement mechanism and case design are discussed in detail during an airport construction.
