根据施工电流值控制粉喷桩桩长的现场试验研究

Site Test Research on Length Control of Power-injected Pile According Electricity in Working

在实际施工中,粉喷桩桩长的确定是一个重要问题。考虑到在实际施工中软土地层空间分布状态的复杂性,依据工程勘察提出的工程设计桩长难以满足实际场地的处理需要。在乐温高建公路粉喷桩软基加固工程中,认为以施工电流值控制桩长大小可以有效地弥补这一需要,并予以实施,取得一定的技术经济效益。工程中所得的相关试验数据和结论对同类工程具有一定的参考价值。

How to determine the length of power-injected pile is a important problem in practical project. Considering the complex special distribution of soft earth stratums in fact, the length of pile by prospecting will be unsatisfied to the requirement of improvement. The author participated in a project of improvement of soft ground by power-injected pile, put forward controlling the length of pile by the intensity of working current, put it in practice and succeeded considerable technical and economic benefits. The experimental data and conclusion from engineering project is valuable to similar projects.
