| 摘 要： | 利用Abaqus建立二维有限元模型,对地墙成槽开挖过程进行数值模拟分析,研究槽段周围土体的应力状态和地表沉降规律及槽段开挖深度、泥浆重度对地表沉降的影响,并将计算结果与实测值进行对比分析.结果表明,地墙成槽开挖将引起槽壁附近土体水平应力发生变化;不同开挖深度、泥浆重度对槽段开挖引起地表沉降的影响显著;数值计算的地表沉降...

| Abstract: | The construction influences of a diaphragm wall panel are simulated by the two-dimensional finite element method.The stress state and settlement of adjacent soil,the influence of slurry weight and the depth of excavated trench are studied.Computer results show that the slurry trench construction causes the change of the horizontal stress of adjacent soil.Both the slurry weight and the depth of excavated trench have significant effects on the ground surface settlement. |
