摘要

为了在离心机试验中模拟降雨引起的滑坡，设计和使用了一套降雨模拟系统。这套系统的构成主要是针对离心试验的特殊要求进行设计的。所采用的特殊技术可以均匀分配雨水，将雨滴的尺寸效益和科氏加速度引起的雨滴偏移最小化，实现了不同强度和历时的降雨模拟。通过一个降雨条件下砂土边坡的离心模型试验，成功应用了该套降雨模拟系统，研究了边坡中的降雨入渗过程。

Abstract

A rainfall simulation system is designed and used in centrifuge modelling of rainfall-induced landslides. The configuration of this system is described in terms of techniques special for centrifuge tests. These techniques allow the system to distribute raindrops uniformly and minimize the size effect of raindrops and the inclination of raindrops due to Coriolis effects. Hence this system is able to simulate rainfall with different intensities and durations. The function of the simulation system is verified during an infiltration process in a sand slope test in the centrifuge.
