【摘要】 本文从水利工程学、水文地质学和岩土力学的角度研究了松散介质地下水库的设计理论。 文中提出了地下水库的储水介质分类法，它能够反映地下水库的本质特征；研究了地下储水空间应满足的基本条件，完善了地下水库的建库条件；探讨了地下水库的设计方法，提出了基于地下水动力学的动态设计法，它考虑了最低地下水位对地下水调蓄的影响，能够反映实际的地下水位，有助于合理地确定地下水库的设计方案和工程规模。 针对地下水库中新出现的井口带有反滤结构的反滤回灌井，作者进行了系统的试验研究和理论研究。首先，研究了反滤回灌井的井流运动特征，进行了反滤回灌井的现场回灌试验，分析了影响反滤回灌井回灌量的主要因素，推导了反滤回灌井的稳定流公式，探讨了稳定流公式中主要参数的影响因素和取值方法，并通过工程实例验证了所推导的稳定流公式的合理性；其次，分析了反滤回灌井淤积堵塞的影响因素，针对淤积堵塞的主要因素，推导了考虑淤积的反滤回灌井的稳定流公式；此外，文中还提出了反滤回灌井回灌池设计的基本原则和方法。总之，通过反滤回灌井的初步研究，解决了反滤回灌井设计和定量计算的基本问题。 文中通过砂土一维等幅循环压缩试验，模拟了地下水位升降引起的含水层压缩和回弹变形，研究了孔隙率降低率随循环次数变化的规律，提出了用孔隙率降低率评价地下水位升降对地下水库库容影响的方法，得出地下水位的反复升降一般不会影响地下水库正常使用的结论。更多还原

【Abstract】 Considering the perspective of water conservancy engineering, hydrogeology and soil mechanics, this paper aims at studying on the design theory of groundwater reservoir in porous mediums.The classification method for groundwater reservoir basing on water-storing medium is proposed to reflecting the essential characteristics of groundwater reservoir. Basic conditions for underground water-storing structures are discussed, groundwater reservoir forming conditions are consummated. Based on groundwater dynamics, the dynamic design method for groundwater reservoir is proposed, it considers the influence of the lowest groundwater level upon groundwater regulation, it can reflect the real groundwater elevation, and reasonably determine the design scheme and project scale of groundwater reservoir.The recharge well with filter layer is constituted of general recharge well and recharge pond, the recharge pond locates the mouth of the recharge well and has filter function. The steady flow calculation and structure design for recharge well with filter layer is researched systematically. Firstly, the well flow characteristic of recharge well with filter layer is analyzed, and field recharge test of recharge well with filter layer has been done, and main influence factors upon recharge volumes are analyzed, and steady flow formulae are deduced, and parameters in steady flow formulae are studied, and the rationality of steady flow formulae is validated through examples. Secondly, siltation factors of recharge well with filter layer are analyzed, the steady flow formulae of recharge well with filter layer are obtained when the surface of recharge well is silted. Another, the basic design principle and design method of recharge pond for recharge well with filter layer are studied. The design and calculation of recharge well with filter layer are solved.Through doing one-dimensional equal amplitude circulating compression test on sand, the compression and resilience deformations of the aquifer are simulated with the groundwater level rising or falling, the change of regulation for reduction rate of porosity with circulating number is constructed, the reduction rate of porosity is proposed, the influence of groundwater level rising or falling upon the volumes of groundwater reservoir is evaluated by the reduction rate of porosity, a conclusion is obtained that rising or falling of groundwater level will can not affect using of groundwater reservoir.更多还原
