发布时间:2018-11-15 10:25
【摘要】:马普托(Maputo)大桥是莫桑比克首都马普托市跨越马普托湾的第一座跨海大桥,大桥北侧(Maputo)侧锚碇为重力式锚碇,锚碇基底基岩为第三纪泥岩(半成岩)。通过现场承载力及摩阻力试验,研究了锚碇基底半成岩的地基承载力及基岩-混凝土胶结面的抗剪强度,试验结果表明,锚碇基底半成岩承载力及摩阻力均满足设计取值要求。
[Abstract]:The Maputo (Maputo) Bridge is the first sea crossing bridge in Maputo, the capital city of Mozambique. The (Maputo) side of the bridge is gravity Anchorage to the north of the bridge, and the basement rock is Tertiary mudstone (semi-diagenetic). Through field bearing capacity and frictional resistance test, the foundation bearing capacity and shear strength of rock-concrete cementation surface of Anchorage basement semi-diagenesis are studied. The test results show that the semi-diagenetic bearing capacity and frictional resistance of Anchorage basement meet the requirements of design.
