[摘要]通過GRLWEAP程序計算分析了錘墊、樁墊的剛度及厚度對打樁過程的影響,并總結(jié)得到了相關規(guī)律,可為電力工程沉樁可行性分析評價提供重要參考依據(jù)。結(jié)合工程實例,利用GRLWEAP程序在沉樁前進行沉樁可行性研究,選定打樁系統(tǒng)、預估基樁沉樁過程參數(shù)、判定沉樁難易程度,使沉樁工作順利開展,實踐證明該方法是必要且有效的。

 

[關鍵詞]PHC樁; GRLWEAP; 打樁系統(tǒng); 樁墊; 錘墊

Abstract:The effects of thickness and stiffness of pile cushion and hammer cushion on pile driving process were analyzed by GRLWEAP software, and the related laws were summarized, which provided important reference for feasibility evaluation of pile sinking in electric power engineering. Combining with practical engineering project, feasibility research on  pile sinking was carried out by GRLWEAP before pile sinking, with selection of pile driving system, estimation of the parameters in the process of pile sinking, determination of the difficulty of pile sinking, to make the pile sinking work smoothly. Practice proved that the method was necessary and effective.

Keywords:prestressed highintensity concrete pile; GRLWEAP; pile driving system; pile cushion; hammer cushion
