文章对苇塘一井奥灰水害治理的各实施方案进行了叙述和比较:作者认为在采用堵、排、截和放的四种方案中,只有放才能达到治水目的。前三种方案都造成了浪费。造成浪费的原因是:对治水中的水害补给源不清;对导水断层走向、倾向多变性认识不足:对动水注浆中应投骨料的原则不明,而盲目施工所致。 The article described and compared the implementation schemes of the treatment of ordovician limewater in Weitang. The author thinks that only four of the four schemes of block, row, cut and release can only achieve the purpose of water treatment. The first three programs have caused waste. The reasons for the waste are as follows: unclear supply source of water damage in water treatment; lack of understanding of water diversion fault tendency and variability: the principle of the castable material in dynamic water grouting is unknown and blind construction results.
