摘要
琼北地区广泛分布着玄武岩残积土,结合海口美兰国际机场二期扩建飞行区地基处理试验段工程实例,总结琼北玄武岩残积土的岩土工程特性,选取原位测试指标作为强夯法有效加固深度的判别标准.通过地基处理前后的静力触探试验、标准贯入试验、重型动力触探试验对比分析,探讨强夯法加固玄武岩残积土的有效加固深度,该项工作可供琼北地区同类地基处理工程借鉴.
Basalt residual soil is widely distributed in northern Hainan area. Based on the ground treatment test section of Haikou Meilan International Airport Extension Project, the geotechnical characteristics of basalt resid-ual soil in northern Hainan area are summarized; in-situ test indicators are chosen as the criteria for effective improvement depth by dynamic consolidation. Through the data contrastive analysis of static penetration test, standard penetration test and heavy dynamic probe test, the effective improvement depth of basalt residual soil by dynamic consolidation is discussed, which provides a valuable reference for similar engineering.
