FACTORS AFFECTING THE VERTICALLY COMPRESSIVE BEARING CAPACITY OF DX PILES
-
摘要: 对影响DX 挤扩灌注桩竖向抗压承载力的诸多因素: 桩身、承力盘(岔) 的直径大小, 承力盘(岔)的数量、间距和位置, 承力盘(岔) 端部土层的特性, 盘腔的首次挤扩压力值及成孔成桩的施工工艺和施工质量等予以介绍。Abstract: In this paper, the different main factors affecting the vertically compressive bearing capacity of DX piles are described. The above-mentioned factors comprise the diameters of pile shafts, branches bearing and bulbs bearing, the numbers, intervals and places of branches bearing and bulbs bearing, the characteristic of bearing strata of branches bearing and bulbs bearing, the pressure value of extrusion first time, the construction technologies and qualities of piles.
