摘要
打桩前必须对打桩过程进行计算分析,以确保安全。以6m开口钢管桩为研究对象,用GRLWEAP软件对打桩的动力学过程进行了分析。采用波动方程法模拟打桩过程中承载力、贯入度、拉应力和压应力、桩输入能量的变化,以了解打桩过程中可能出现的问题,计算桩能顺利贯入指定的深度。
To ensure safety, it's necessary to analyze the piling process before driven. This article takes 6m diameter open steel pile as the object and uses GRLWEAP to analyze the dynamic process of pile driving. Wave equation is adopted to simulate the bearing capacity, penetration, tensile stress and compressive stress of pile, as well as variation of pile energy input during pile driving, so as to find the problems that may appear in piling and calculate the appointed depth that pile can be drove into.
