摘　　要：饱和土有效应力传感器是岩土介质力学测试中所急需的一种传感器,通过对饱和土中孔隙水压力传感器的分析,建立了传感器滤水结构动态特性的数学模型,通过对该模型动态响应特性的分析,设计的传感器能有效应用于动态荷载作用下饱和土有效应力的测试,试验和实际应用效果良好。The effective stress sensor is a sort of imperative sensor in soil mechanics testing. The math model of filter system is established by analyzing pore water pressure sensor in saturated soil. By analyzing dynamic respond characters, the sensor is designed that it can be applied availably to measurement of effective stress under dynamic load. The work is well in experiment and practical application.
