| 摘 要： | 针对由于下游排水棱体失效而导致某土石坝坝体浸润线比较高、坝坡安全系数不能满足规范要求的情况,通过削坡和重建排水棱体对其进行整治,再利用GeoStudio2007软件对该土石坝的稳定渗流期进行有限元分析,对比分析整治前后的渗流场和坝坡抗滑稳定性,验证了整治措施对坝体渗流和稳定性的改善作用。

| Abstract: | Slope cutting and drainage prism reconstruction of one earth-rock fill dam are executed as the phreatic line of the dam body is higher and the safety factor of dam slope cannot be satisfied, which are resulted from the failure of the drainage prism at downstream. Then, GeoStudio2007 is applied for analysis of the stable seepage-flow peril in term finite element. Through comparison and analysis of seepage field and stability of dam slope against sliding before and after the treatment, it is verified that the treatment measures contrib- ute to improve seepage flow and stability of dam body. |
