摘　　要：统计了不同深度测层的群井降水附加应力从开始传递到水位响应的间隔时段，在此基础上建立了应力在地层中传递深度－时间相关模式，进行了有关参数反演，并结合相关地质、气象等资料，提出了岩层空隙比－应力传递速度的相关模型。该模型说明了应力传递速度与岩层结构、构造的内在联系，为不同类型应力在不同空隙比岩层中的单层传播速度、组合层段传播所需时间计算提供了简单、有效的方法。We have made statistics on the interval time from the beginning of the rainfall stress transfer to water level response for different depths of wells. On this basis the correlation mode of the stress transfer depth time in the stratum is established. The relevant parameters are calculated by inversion method. The correlation model of rock hole ratio stress transfer velocity is suggested with these parameters and geological and meteorologic data. This model indicates the inner relation between the stress transfer velocity and the rock layer structure. It provides a simple and effective method for the calculation of stress transfer time in single and multilayer with different hole ratio. It is also helpful for identification of interference caused by rainfall stress to the water level of deep wells.
