摘要
以某百米级黄土均质坝工程为依托,以掺砾高均质土坝为研究对象,应用数值仿真分析对坝体的应力变形与掺砾量的关系进行研究,探究减小高均质坝坝体沉降变形的途径,避免坝体由于变形过大而开裂。结果表明:提高筑坝材料掺砾比例是控制高黄土均质坝坝体变形的有效途径。但随着掺砾比例的增加对坝体变形的改善程度趋于稳定,掺砾25%以上对于控制坝体的沉降效果明显。研究成果可为类似高黄土均质坝工程建设提供借鉴。
Based on a 100-meter-level loess homogeneous dam project and a gravel-mixed high homogeneous earth dam as the research object,numerical simulation analysis is used to study the relationship between the stress deformation of the dam body and the amount of gravel mixed,and to explore ways to reduce the settlement deformation of the high homogeneous dam body and avoid cracking of the dam body due to excessive deformation.The results show that increasing the gravel ratio of dam construction materials is an effective way to control the deformation of the high loess homogeneous dam body.However,as the gravel ratio increases,the degree of improvement in the deformation of the dam body tends to stabilize,and gravel mixing of more than 25%has a significant effect on controlling the settlement of the dam body.The research results can provide reference for the construction of similar high loess homogeneous dam projects.
