| 摘 要： | 通过工程实例,探讨了堤后大面积CFG桩基对北江大堤渗流场产生的影响,根据分析结果,按满足规范要求并且不降低原堤防压渗标准的原则,提出在堤后采用增加压渗的处理方法,使得压渗安全系数比工程前略有提高,有效地保证了北江大堤的安全,为类似问题的处理方法提供参考。

| Abstract: | By an engineering example, the impact of of CFG pile after a large embankment on the Great Beijiang levee seepage field has been discussed. According to the analysis results, abiding by regulatory requirements and the rules of no decrease on original embankment pressure infiltration standard, and countermeasures have been put forward through increasing pressure infiltration behind the levee, which can increase infiltration pressure safety factor, and effectively ensure the safety of the North River levee to provide a reference method for handling similar problems. |
