粉喷桩及复合桩在复杂软土地基中的应用

On the application of the dry jet mixing piles and composite piles in the complex soft soil foundation

通过工程实例,分析了水泥搅拌干法和湿法在加固含水量较高的软黏土地基中的区别,阐述了粉喷桩与挤密砂桩结合形成水泥砂土复合桩,与振动微型素混凝土桩结合形成素混凝土劲芯复合桩的不同特点,实践证明该工程采用的处理方案是可行的。

According to construction examples, the paper analyzes the differences of the dry method and wet method of the cement mixing construction in consolidating the soft clay foundation with higher water content, indicates the features of the composite piles of the concrete and sand combined by the dry jet mixing pile and the compaction sand piles as well as the features of the composite piles with stiffness core formed by the combination of the dry jet mixing pile and the micro vibration concrete piles. It is proved by the practice that the treatment of the construction is feasible.
