桩基挡土墙在河道边坡护砌中的应用

Application of pile retaining wall in river slope protection

根据场地地质条件、周边环境要求,挡土墙无法通过增大基础底板尺寸来提高抗滑稳定时,采用以桩基为承载主体的桩基挡土墙,可以在不增加占地、不影响周边建筑物地基稳定的条件下满足挡土墙抗滑稳定。本次通过对桩基挡土墙案例的计算分析,为今后类似河道边坡护砌工程提供了一定的参考。

According to the geological conditions and the surrounding environment,when the ability ofanti-sliding cannot be improved by widening the foundation size,pile foundation retaining wall with pilefoundation as the main bearing body can meet the anti-sliding stability of retaining wall withoutincreasing the land occupation and affecting the stability of surrounding buildings.Through thecalculation and analysis of the case of pile foundation retaining wall,the reference was provided in thispaper for the similar river slope protection engineering in the future.
