摘要:
对深圳已填埋11年的垃圾场碎石桩加固现场取样进行室内试验及原位静力触探试验,结合国内外相关试验成果,分析原位静力触探试验与取样室内试验结果,得到垃圾土三轴固结不排水剪内摩擦角、干密度与静力触探试验锥尖阻力、侧摩阻力的相关规律.经碎石桩复合地基现场载荷试验和复合地基计算复核,按原位试验确定的碎石桩处理垃圾土复合地基承载力合理安全.
Abstract:
The results of laboratory test and cone penetration test at landfill improvement site by stone column,which had been covered for eleven years, were studied. The relation of the results of laboratory test and cone penetration test have been analyzed. The results show that there is regular relation between friction angle of consolidation undrained test with cone tip and lateral friction resistances,there is good relation of dry-density with cone tip and lateral friction resistance. Comparing the results of loading test with that of calculation of bearing capacity of the composite ground improved by stone column,it is reasonable and safety that bearing capacity of composite ground by stone column is determined by in-situ test.
