摘要
通过研究地基土指标,由施工期指标进入蓄水期指标时完建坝体与地基应力场的重分布,结果表明,重分布的变幅是相当巨大的,甚至于会影响到在砂砾石地基上能否建造某种胶凝砂砾石坝的决策。故对此进行分析研究,分析地基土含水量饱和工况强度。
This paper studied the redistribution of stress field of finished dam and foundation when the foundation soil index changed from construction period into water storage period. It was found that the stress redistribution was so huge that it may produce influence on building cement sand and gravel dam on sand and gravel foundation.
