| 摘 要： | 滨海地区利用吹填淤泥或砂围海造陆将在地基上部形成一潜水含水层,但现有方法大都依赖于Theis非稳定承压含水层井流理论求解水文地质参数,进行降水设计,缺乏合理性。结合广州港南沙港区粮食及通用码头软基试验区科研项目,利用Neuman非稳定井流理论进行潜水含水层水文地质求参,将所得参数进行有限差分分析,数值结果与水位监测成果一致。工程实例表明,该方法合理、可靠,为类似应用提供了一种新途径。

| Abstract: | In the coastal area,an unconfined aquifer will be formed on the upper part of the foundation by dredging and filling silts or sands to reclaim land,but the most existing methods are relying on the Theis,a well flow theory of non-steady confined aquifer to solve the hydro-geological parameters and conduct precipitation design that is lack of rationality.By applying the Neuman unsteady well flow theory to derive the hydro-geological parameters of unconfined aquifer and then using the finite-difference method ... |
