大面积 CFG 桩基对北江大堤的渗流场影响分析及加固对策探讨

摘要

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 .%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。
