| 摘 要： | 某高桩梁板码头在运营过程中出现明显的晃动现象。采用三维有限元数值动力分析方法,取码头的1/2排架系统计算结构的自振频率,采用m法模拟桩周土对桩的约束作用,用ANSYS程序进行计算分析不同处理措施下码头第一振动频率的提高值。计算分析表明:采取抛石固桩、桩内灌注混凝土和增设钢撑后,码头第一振动频率提高10%～84%,能有效解决码头晃动问题。

| Abstract: | A beam-slab piled wharf appeared sloshing in the process of operation.Using three-dimensional finite element analysis,we computed the natural frequency of a half of the wharf bent system,simulated the restraint function of soil effecting piles by m method,and analyzed the wharf's first vibration frequency about different treatment measures by ANSYS software.The calculating and analyzing results show that through rubble filling,concrete pouring into the pile,and welding of steel pipe on the wharf bent,the fi... |
