砂土地基大直径混凝土灌注长桩受力性状试验研究
Study on behavior of stress of large diameter and concrete bored long pile in sand soils
【摘要】 通过对砂土地基中灌注桩竖向静载试验资料分析,确定了单桩承载力、研究了持力层为卵石层的长桩轴力的传递规律、沉降量与桩身压缩量的关系及桩侧阻力发挥机理。
【Abstract】 This article analyzed the verticle bearing capacit of concrete bored pile,determine the bearing capacity of single pile,study the load transfer of long pile in sand soils with bearing strata of pebble,the sedimentation and the compression of the pile,and side friction of pile.
