| 摘 要： | 某港口堆场地基由砂土吹填而成,地基承载力约为65kPa,为使地基达到150kPa的承载要求,必须对该吹填砂土地基进行处理。根据场区不同的地层条件、使用功能和地基强度,设计分别采用插板振冲、插板强夯、不插板强夯三种加固方法进行试验。试验检测结果表明,三种加固方法处理后的地基承载力均能满足设计,插排强夯效果最佳。

| Abstract: | The objective port storage yard built on a dredger fill sandy soil foundation needs to be reinforced as to meet the required bearing capacity of 150 kPa from its original one of 65 kPa.Three reinforcement methods as vibro-compaction method with drainage shaft,dynamic compaction with drainage shaft and without drainage shaft were adopted as experimental tragedies for treating the storage yard based on the stratum condition,functions and foundation intensity of the storage yard.The results reveal that the three reinforcement methods are all advisable in that the bearing capacity of the yard after treatment meeting the design requirement.The dynamic compaction with drainage shaft is the best one ground on its excellent efficiency. |
