摘要
总结了现阶段冻土区桥梁桩基础抗震试验研究的主要任务,从试验的目的、优势、设计和不足等方面对冻土三轴压缩试验、桩-冻土体系拟静力试验和地震模拟振动台试验的研究现状进行了系统的总结与分析,提出了相应的改进措施和发展方向。考虑到室内试验中桥梁桩基础-冻土相互作用体系实施难度的问题,提出了采用子结构试验方法开展冻土区桥梁抗震试验的思路。
This paper provides a comprehensive overview of the current research on seismic testing of bridge pile foundations in the frozen soil region.The purpose,advantages,design,and shortcomings of the frozen soil triaxial compression test,the pile-frozen soil system pseudo-static test,and the seismic simulation shaking table test are systematically summarized and analyzed;corresponding improvement measures and development directions are proposed.Considering the challenges associated with implementing the interaction system between the bridge pile foundations and the frozen soil in laboratory experiments,the idea of utilizing the substructure test method to conduct seismic testing of bridges in the frozen soil regions is proposed.
