摘要
通过建立等壳水电站的非溢流坝段的准三维有限元模型,模拟了坝体排水管和排水廊道、上下游防渗层、坝基灌浆帷幕、坝基排水管和排水廊道等,对正常蓄水位工况下坝体、坝基的渗流总水头、压力水头、渗透比降、坝基扬压力分布及渗流量进行了计算分析,验证了坝体和坝基的防渗排水措施的合理性。
By establishing a quasi three-dimensional finite element model of the non-overflow section of the Dengke Hydropower Station,dam drains and drainage corridor,the impervious layer upstream and downstream,dam foundation grouting curtain,dam foundation drains and drainage corridor etc.are simulated.A computational analysis is made of seepage total head,pressure head,seepage gradient of dam bodies and foundation and dam foundation uplift pressure distribution and seepage flow under the normal storage level conditions.The rationality of dam bodies and foundation anti-seepage drainage measures has been proven.
