水泥粉喷桩检测与分析

Analysis and Investigation of Cement Powder Spray Pile

通过分析对成桩一年以上的水泥粉喷桩的大量取芯和静载检测结果 ,得出结论 :复搅是工程质量的保证 ;粉喷提高强度效果对淤泥不逊于粘土 ;粉喷桩系摩擦形桩 。

According to the great amount of core catching and static loading tests more than one year,it is found repeatedly that spray and mixing would guarantee the quality.The effect of increasing the stength by powder spray for clay is as good as for muck.Spray pile is frictional pile,therefore increasing the pile length for higher bearing capacity is considesed to be unsuitable.
