摘要

汶川特大地震给四川省德阳市水库土坝造成了不同程度的震损。依据德阳市境内66座高危以上险情水库土坝震害考察资料和现场震害调查结果

对震损水库土坝进行了分类统计

研究其震害特征及震损原因

结果表明:小型水库均质土坝在此次地震中震损数量最多、险情严重

且震害类型丰富;典型震害包括裂缝、滑坡、沉陷、渗漏以及泄水建筑物与其它附属设施损坏。以德阳市3座典型震损水库土坝为例

分析了水库土坝的基本情况、震前运行状况及震损情况

进而提出了有效的震后抢险措施。

Abstract

The Wenchuan great earthquake has resulted in different degree damage to reservoir earth-rock dams in Deyang City of Sichuan Province.Based on the seismic damage investigation data and filed survey on 66high-risk damaged reservoirs in Deyang City

the seismic damage features and causes are discussed through classified statistics on the damaged dams.It is found that small earth dams and homogeneous earth-rock dams are apt to be damaged and suffered the most serious damage during the earthquake.The seismic damage types of the dams are diversified including the crack

the landslide

the subsidence

the leakage as well as the damage to discharge structures and other subsidiary facilities.Taking three reservoirs earth dams in Deyang City as examples

the project general conditions

pre-earthquake running situation and seismic damage phenomena of damaged dams are analyzed in order to propose the effective emergency measures after earthquake.
