Drainage well layout calculation method for relieving soil secondary salinization
The invention relates to a drainage well layout calculation method for relieving soil secondary salinization. The method comprises the steps that the critical burial depth of salinized underground water is determined; hydrogeological parameters of a research area are determined; the underground water drawdown of a salinization area is determined; the influence radius of drainage wells is calculated; and reasonable layout of the drainage wells in the salinization area is determined. By taking the salinized underground water critical burial depth as a management and control target, the reasonable underground water drawdown of the secondary salinization area is accurately determined, and the influence radius of the drainage wells is determined by analyzing the influence of water pumping of the drainage wells on the underground water level, so that the underground water level of the secondary salinization area is accurately reduced by reasonably arranging the drainage wells, and secondarysalinization caused by the over-high underground water level of a local area due to unsmooth drainage of irrigation return water is remarkably and effectively relieved. The method has universality forsolving the problem of soil salinization caused by the too high underground water level, and reliable theoretical and technical supports are provided for guiding treatment of soil salinization and reasonable development and utilization of underground water resources.
本发明涉及一种改善土壤次生盐渍化的排水井布设计算方法，包括确定盐渍化地下水临界埋深；确定研究区域水文地质参数；确定盐渍化区域地下水降深；计算排水井的影响半径；确定盐渍化区域排水井的合理布设。本发明以盐渍化地下水临界埋深为管控目标，精准确定次生盐渍化区域地下水合理降深，通过分析排水井抽水对地下水水位的影响，确定排水井的影响半径，从而通过合理布设排水井来实现精准降低次生盐碱化区域的地下水水位，达到显著有效改善因灌溉回归水排水不畅导致局部区域地下水位过高而导致的次生盐渍化。该方法对地下水过高导致土壤盐渍化问题的解决具有通用性，为指导土壤盐渍化的治理和地下水资源合理开发利用提供可靠的理论与技术支撑。
