Abstract

瓶塞型防震坝，利用不与地基相连接的拱形塞坝在水压作用下塞住由底坝，瓶颈式肩坝组成的坝口。从而使水坝具有在强地震应力，裂变下不致造成坝体垮塌，大水一泻千里的后果。

Description

一种瓶塞型防震坝
瓶塞型防震，为避免水库大坝可能因地震力损坏而造成几百米的高头大水一泻千里，倾刻将下游演为汪洋的可怕局面的出现而提出一种新的坝型。
如图一，依岸就势我们可设围堰修筑瓶颈式肩坝(2)，围栏修桥墩修底坝(1)，其长度、高度由蓄水高度决定，但主要受力点应在肩坝上。塞坝(3)可先在上游预制，漂来底坝处组装，以缩短工期。各结合面宜采用弧面。
该型水坝在各向地震应力、裂变作用下，都有阻挡高头大水奔腾而出的能力。由于工期短，制造难度相对小些，所以虽比现有坝型大，但造价不一定高。
