摘要
通过GRLWEAP程序计算分析了锤垫、桩垫的刚度及厚度对打桩过程的影响,并总结得到了相关规律,可为电力工程沉桩可行性分析评价提供重要参考依据。结合工程实例,利用GRLWEAP程序在沉桩前进行沉桩可行性研究,选定打桩系统、预估基桩沉桩过程参数、判定沉桩难易程度,使沉桩工作顺利开展,实践证明该方法是必要且有效的。
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.
