摘要
在心墙土石坝设计中,心墙是坝体的防渗部分,它对坝的稳定起着至关重要的作用.结合工程的实际情况,考虑非饱和区的影响,在不同心墙体积的情况下,分别对其进行渗流计算分析,探讨渗流场的分布情况和自由面的变化规律,为大坝结构设计和施工提供基础资料和参考依据.
In designing the earth-rock dam with core wall, core wall is impermeable part of the dam; it plays an important role in the stability of dam. Taking the actual situation of project as a background, and considering the influence of the unsaturated zone of the earth-rock dam and size of core wall in different circumstances, seepage calculation is carried out to discuss the distribution of seepage field and change rule of free surface. The result will provide the basic data and reference for the design and construction of earth-rock dams.
