薄膜式土压力分布传感器研发及试验研究
Experimental Research and Development of Thin-Film Soil Pressure Distribution Sensor
摘要
Abstract
With the advances in the Geotechnical mechanics and Engineering,the research and development on new earth pressure sensors are becoming more and more important. The current study developed a thin-film soil pressure distribution test sensor-overall thickness was less than 0. 2 mm, by composite materials. The study introduced the structure and mechanism of the sensor and conducted a pretest on its sensitivity. It was shown that double-layer structure sensor had higher sensitivity. Moreover, the basic performances of the sensor were tested through large-scale model experiment,which demonstrated that the sensor was reliable. The thin-film sensors can be applied into soil pressure cell as its advantages include the smaller size( large density test) ,the smaller T/D( less disturbance to soil) ,convenient wire layout and large deflection bending( suitable for curved surface) and the like.关键词
