文中给出了用汉克尔-拉普拉斯变换技术得到的点沉基本解。在此基础上，提出了地面沉降模拟的近似求解方案。利用叠加原理和Duhamel原理对曼谷地区地下水开采引起的地面沉降量进行了预测。这一简化模型也是预测油气等其他流体开采引起的地面沉降的有用工具。
Paper presents a point‐sink fundamental solution obtained by the Hankel‐Laplace transform technique. Based on this solution, an approximate solution scheme is developed for land‐subsidence simulation. The mathematical model was then applied to predict the subsidence in Bangkok area due to ground‐water recovery by using the superposition and Duhamel principles. This simplified model is also a useful tool for predicting land subsidence due to other fluid recovery such as oil and gas.
