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。
The Maputo Bridge is the first cross-sea bridge across the Maputo Bay in Maputo,Mozambique's capital. The north side anchorage of the bridge is a gravity anchor and the basement bedrock is a Tertiary mudstone( semi-diagenetic).The bearing capacity of foundation and the shearing strength of bedrock-concrete cementation surface are studied by field bearing capacity and friction resistance test. The results show that the bearing capacity and friction resistance of the semidiagenetic rock of the anchor foundation are all satisfied and it can be used as a reference for similar engineering.
