补充资料:均质土坝
      用一种筑坝材料筑成的土坝(图1)。一般用粘性土料,也有全部用透水料筑成。均质土坝适用于:①当地只有一种筑坝材料的情况;②由于坝坡缓,填筑高坝需要工程量大,故适用于中低坝;③土料施工受气候影响,故适用于严寒和降雨季节都比较短的地区;④透水料均质土坝仅适用于滞洪水库,且宜用中粗砂填筑,砂卵砾石透水性大,均匀粉细砂易液化,都不宜用。
  
  
  均质土坝优点:①材料单一,工序简单,各工序间干扰少;②与坝基、岸坡及混凝土建筑物的接触渗径比较长,可简化防渗处理。缺点:①设计的坝坡常较其他坝型缓,使填筑工程量增加;②由于土料施工受严寒及降雨气候影响,使这种坝型在上述地区的使用受到限制;③如建在弱透水基础上又未采取适宜的坝内排水措施,坝体浸润线较高;④当库水位迅速降落,粘性土孔隙水不易排出;⑤施工期因自重而产生的孔隙压力消散缓慢,对坝坡稳定不利。
  
  
  坝体应设置排水以降低浸润线。常用棱体排水或褥垫排水。如坝体水平和垂直向具有相同透水性,褥垫排水能有效降低坝体浸润线(图2a)。鉴于填土经碾压后沿层间的水平向透水性常比垂直向大,虽设褥垫排水浸润线仍将上抬(图2b),故宜在坝内设置竖式排水(图3),下接褥垫排水,以拦截运行期水平向渗水,保证下游坝体处于干燥状态,并加快施工期排水固结降低孔隙压力。必要时可在坝体设置若干上游水平排水层,当水库水位降落时可使坝内孔隙水流向由向上游改为向下,有助于上游坡稳定(图4)。
