1、-某水利工程土石坝初步设计(沥青混凝土防渗墙)-第 51 页河北工程大学水利水电工程专业毕业论文毕 业 论 文题目:西南地区某水利工程土石坝初步设计 姓 名:赵 龙学 号:110290302指导老师:屈春来老师2015年5月23日摘 要该江位于我国西南地区,本工程拦河坝沥青混凝土心墙坝。由于山区水位暴涨暴落,所以设置成兴利库容和拦洪库容完全不结合,即正常蓄水位和汛限水位均为2822.5米。本设计是侧重于坝工部分以挡水建筑物和泄水建筑物为主的土石坝水利枢纽设计。第一步,通过调洪演算得到最佳的溢流堰孔口净宽和堰顶高程方案,比较不同类型的土石坝在施工特点,技术经济等方面的优劣,最终确定大坝坝型为沥青
2、混凝土心墙坝,并且初定了大坝的轮廓尺寸。然后通过土料设计,对照指标确定了砂砾料场的位置。再选择坝体的三个典型断面对大坝进行渗流计算,通过水利计算来确定渗透坡降是否满足要求。然后通过vb编程进行坝坡稳定分析,最终进行坝体细部构造设计。第二步,进入主要建筑物设计阶段。确定出大坝的型式及坝址和坝轴线。另外确定该枢纽的组成建筑物,包括挡水建筑物、泄水建筑物、水电站厂房等。最后进行细部构造设计,设计土石坝与地基、岸坡的连接,并设置相应的大坝安全监测。本设计以碾压式土石坝设计规范SL274-2001为基本设计依据,外加参考了与土石坝的有关资料和书籍。 关键词: 沥青混凝土心墙坝 大坝剖面基本尺寸 渗流计算
