【摘要】:馬普托(Maputo)大橋是莫桑比克首都馬普托市跨越馬普托灣的第一座跨海大橋,大橋北側(cè)(Maputo)側(cè)錨碇為重力式錨碇,錨碇基底基巖為第三紀(jì)泥巖(半成巖)。通過(guò)現(xiàn)場(chǎng)承載力及摩阻力試驗(yàn),研究了錨碇基底半成巖的地基承載力及基巖-混凝土膠結(jié)面的抗剪強(qiáng)度,試驗(yàn)結(jié)果表明,錨碇基底半成巖承載力及摩阻力均滿足設(shè)計(jì)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.
