| 摘 要： | 目前,灰场已接近三级子坝贮灰限制高程,为满足电厂后续贮灰的要求,拟在三级子坝坝前沉积灰上采用灰渣作为筑坝材料进行四级子坝加高。为保证安全,进行四级子坝加高时需进行子坝加高方案论证。根据试验及计算分析结果可知,对于三级子坝,在正常工况和可能出现最不利的工况条件下,三级子坝下游边坡的稳定性满足有关规范要求,可以进行子坝加高。四级子坝的加高方案采用坝高为5.0m,下游边坡坡度不陡于1:3.5,上游坡坡度不陡于1:2.5,坝顶宽度5.0m,子坝的筑坝材料可采用库内沉积的粉煤灰。

| Abstract: | Now the ash＇level of Xiangyanggou will arrive limit ash storage elevation, it need build the fourth subdam used ash and slag. so it need heightening scheme research of fourth subdarn. According to the experiment result and calculation analysis, the stability of downstream slope of third subdam meet the code, and can heighten the third subdam. The fourth subdam＇s height is five meter, and the downstream slope is less than 1： 3.5, the width of dam crest is five meter, the material can use ash and slag. |
