“加固为主,培修为輔”这是下游的修防方針。那么这个方針意味着什么呢?我觉得这就是說:大堤已达到相当高程,而可能造成潰决的主要危險,是堤防还存在着許多弱点,因而消除大堤存在的弱点就成为当前下游工作的主要方面。由于堤防存在的問題是复什的,所以加固措施也是多种多样的。几年來我們曾經修做了許多“填塘固基”、“抽槽换土”、“粘土斜牆”、“粘土复盖”“抽水窖堤”等工程,并普遍進行了大堤錐探。無疑 “Reinforcement, training supplemented” This is the downstream repair policy. So what does this policy mean? I think this means that the main danger of the embankment, which has reached a certain height, is that the embankment still has many weaknesses. Therefore, the elimination of the weakness of the embankment has become the main downstream work aspect. Due to the problems existing in embankments, the reinforcement measures are also varied. Over the past few years we have done a lot of “fill pond solid foundation”, “pumping tank replacement soil”, “clay sloping wall”, “clay cover” “puddle dike” and other projects, and the general embankment cone exploration. undoubtedly
