摘　　要：介绍了用于非饱和土边坡试验的人工模拟降雨设备的组成、主要设计参数和控制降雨强度的方法,着重介绍了总降雨量、径流量、孔隙水压力(吸力)、含水量4种基本数据测量所需的仪器及其埋设方法,给出应用实例和比较分析,并设计了在重庆某高速公路填土边坡上的非饱和土特性监测计划和人工降雨装置.This paper describes the equipments used in artificial rainfall simulation tests, the main designing parameters, the methods of controlling the artificial rainfall intensity; and specially introduces four sets of instruments and their arrangements used for measuring the total rainfall, the surface runoff, the pore-water pressure （suction） and the soil moisture respectively. The paper also gives several examples of field investigation and artificial rainfall simulation tests on unsaturated soil slopes and their analyses and comparisons. Based on these, a field investigation program and an artificial rainfall simulator system are designed for a filled unsaturated soil slope of an expressway in Chongqing.
