渣土桩复合地基属于半刚性半柔性桩复合地基,加固地基效果明显,利用ANSYS有限元软件对渣土桩单桩复合地基承载力进行了数值计算分析,结果表明,桩体、桩间土协调工作性较好;桩与桩间土的压缩模量对复合地基的承载特性影响较大;桩长对提高渣土桩复合地基的承载力效果不明显,应以实际工程地基处理目的为首要考虑因素。
The soil-pile composite foundation belongs to the semi-rigid semi-flexible pile composite foundation, and the effect of reinforcing the foundation is obvious. The bearing capacity of the composite foundation with the single pile of the soil and piles is calculated by ANSYS finite element software. The results show that the soil- The workability is better; the compressive modulus of soil between piles and piles has a greater influence on the bearing capacity of composite foundation; the effect of pile length on improving the bearing capacity of the composite foundation of soil-cement piles is not obvious, so the purpose of actual engineering foundation treatment should be considered factor.
