| 摘 要： | 高洪水位期间,存在蚁害隐患的堤坝易出现散浸、管涌、跌窝和塌坡等险情。通过对各种险情出险特征的分析,可及时准确地判定出险原因,以便采取合理的抢护措施,确保堤坝的安全.对初期渗透漏水的散浸险情应以导浸为主;对蚁穴贯通漏水的管涌险情应及时堵塞进水口,减少土体流失;对跌窝和塌坡等重大险情,则应采取帮土补强、内围堰降压和堆土固坡的综合处理措施.

| Abstract: | During the period of high flood stage, it is easy to cause lots of dangerous situations in those dams in which exist ants hidden dangers, such as seperation seek, piping, collapse and landslide, etc. By analysing the features of various kinds of dangerous situations, the reasons could be correctly decided in order to take reasonable measures to protect the safety of dams. As for the situation of seperation seek, when water seeps through dams at the beginning, dredging should be made as the dominant measure. As for the situation of piping, incoming water should be stopped in time so as to reduce water and soil washing away. As for the situation of collapse and landslide,synthetic measures should be taken. |
