| 摘 要： | 格栅碎石桩是一种在碎石桩中加入格栅套管的复合地基软基处理方法.介绍了格栅碎石桩的施工工艺、作用机理以及检测方法,并通过现场静载荷试验证该技术的合理性.格栅碎石桩克服了碎石桩承栽力低、有效桩长短和压缩变形大等不足,且造价不高,因此该技术在高等级公路、市政工程、建筑工程及港口等工程软基加固中具有广阔的应用前景.

| Abstract: | Geogrid stone cased pile is a way to improve soft soil by restricting stone column with geogrid.The construction and mechanism of action of geogrid stone cased pile are introduced,and furthermore,the rationality of this method is proved by the static load test results.Compared with stone column,geogrid stone case pile has higher bearing capacity and smaller compression deformation and deeper strengthen depth,with a not too high cost.So geogrid stone cased pile has a great application in the project of expre... |
