基于PLAXIS 2D的波浪桩护岸设计研究——以界南河颍河至泉河段治理项目(一期)为例

Research on wave pile revetment design based on PLAXIS 2D software:a case study of the Jienan River section from Yinghe River to Quanhe River in the river management project(Phase I)

以界南河颍河至泉河段治理项目(一期)工程为例,利用PLAXIS有限元软件在不同规格的波浪桩挡土高度和施工工法等设计和施工组合条件下进行了数值模拟计算,分析总结波浪桩桩顶位移、岸后地面沉降的变化规律。选用打入式沉桩法时波浪桩悬臂段挡土高度宜控制在2.0~3.0 m范围,相关成果可为类似工程提供设计参考。

Taking the Jiennan River section from Ying River to Quan River in the river management project(Phase I)as an example,PLAXIS finite element software was used to conduct numerical simulation calculations under different specifications of wave piling,soil retaining wall height,and construction methods.The study analyzed and summarized the variation patterns of wave piling top displacement and bank backfill settlement.When employing the driven pile method,it is advisable to control the height of the cantilever section of the wave piling for soil retention within the range of 2.0 to 3.0 meters.The relevant outcomes can serve as design references for similar engineering projects.
