人工降低地下水位的方法,由于近年来不断的研究和改进,效果日趋完善,大大地扩大了它的应用范围。据国内外实践经验的证明,人工降低地下水位的深度可从几米至数十米,例如武汉修建某工程时,就采用了一层喷射井点,使原有的地下水位降低了十四米多。在苏联的一些工程,例如伏尔加——顿河通航运河、古比雪夫、齐姆良斯 Artificially reducing the groundwater level method, due to continuous research and improvement in recent years, the effect has become increasingly perfect, greatly expanding its scope of application. According to domestic and foreign practical experience, artificially reducing the depth of the groundwater level can range from a few meters to several tens of meters. For example, when building a project in Wuhan, a layer of jet wells was used to reduce the original groundwater level by more than 14 meters. . Some projects in the Soviet Union, such as the Volga-Don River, the navigation river, Kuibyshev, and Zimlens
