土石围堰土石围堰earth and rockfill cofferdam dam)用土石材料修建的临时挡水建筑物(见施工围堰)。土石围堰的结构简单，可以就地取材，施工方便，在水利工程施工中被广泛采用。土石围堰又可分为土围堰，土石混合围堰，堆石围堰等。土围堰可采用各种土料填筑或冲填而成;土石混合围堰用土混合以块石碴填筑;堆石围堰则全部由石料堆筑，另设防渗体。它可以在流水中修建，适用于各种地基。但土石围堰工程量大，易沉陷变形，抗冲能力差，通常用于横向围堰。 土围堰按结构可分为均质土围堰、非均质土围堰，后者设有斜墙或心墙防渗。堰顶宽一般不小于3米，有时可视施工需要(如通行车辆)适当加宽。边坡根据填土料确定，迎水面边坡一般1:2.5一1二3.0;背水面边坡1:1 .75一l二2.5。在透水地基上要采用防渗措施。排水设施是土围堰重要组成部分，它对堰体稳定有利。迎水面水流流速大时，则需设置块石或卵漂石护坡。 土石混合围堰和堆石围堰的边坡坡度，应具有足够抗滑稳定性，一般上下游坡采用1:1 .8。水利枢纽中的土石坝，如果采用河床外隧洞导流方式，全断面截流的堰体往往较高，这样可将堰体作为坝体的一部分，如中国碧口水电站枢纽。但该结合部分的围堰质量应与大坝一致。防渗体与坝壳间，必须铺设反滤层，最小厚度不小于0.3米，设计中力求减少层次。堰体与岸边联接予以充分注意，以防接触面上发生渗漏。必要’时还可修成过水围堰。(葛文辉)tushi weiyan土石围堰(earth and roekfill eoffer-
