摘要
针对某海滨城市围海造陆区域内吹填路基加固的难题,采用插板堆载+井点降水+强夯法的新型工艺进行加固处理,开展试验研究.通过孔隙水压力、表层沉降及土工试验、静载荷试验等指标对试验区进行监测和检测,试验结果表明,该方法可以满足路基对工后沉降的要求,大幅提高地基承载力,而且砂土液化问题也得以解决.
The well point precipitation combined dynamic drainage consolidation method is used to solve the problem of reinforced hydraulic fill roadbed foundation in a coastal city reclamation project. On the basis of wa- ter pressure monitoring, surface settlement monitoring, laboratory soil test and static load test, the results show that well point precipitation combined dynamic drainage consolidation method not only meets the requirement of design and enhances the bearing strength of foundation, but solves the prediction of sand liquefaction.
