长江下游河漫滩地区水泥粉喷桩地基静力触探试验研究

Experimental study on static cone penetration of cement powder spraying pile foundation at the Yangtze River flood land

摘要: 本文根据天然地基、粉喷桩加固后地基和复合地基荷载试验以后地基土的现场静力触探试验结果，分析和研究粉喷桩加固效果和影响范围以及在复合地基循环荷载试验条件下地基土强度变化情况。

Abstract: In this paper,the results of static cone penetration test are summarized by means of a series of test conditions, including natural ground, consolidation foundation by cement powder spraying pile and composite foundation after loading test. Based on the static cone penetration test result,the strength of soil among piles and effect of consolidation are presented and discussed.
