众所周知,量测土压力是比较困难的,因为土介质和结构物材料的变形特性是变化的,所以要求土压力传惑器与土介质或结构材料的变形特性达到完全匹配是不可能的。一个设计得好的土压力传感器,就是在不完全匹配的情况下,使传感器在量测时的工作特性按一定的规律变化,所产生的误差是可知的。一、设计土压力传感器的理论依据 几十年来,国内外对土压力传感器进行了大量的理论和实验研究,如美国的泰
It is well known that measuring earth pressure is more difficult because of the varying deformation characteristics of soil and structural materials. Therefore, it is not possible to require a perfect match between the soil pressure transducer and the deformation characteristics of soil or structural materials. A well-designed earth pressure sensor, is in the case of incomplete matching, so that the sensor in the measurement of the operating characteristics of a certain regularity changes, the error is knowable. First, the design of earth pressure sensor theoretical basis For decades, the earth pressure sensor at home and abroad a lot of theoretical and experimental research, such as the United States of Thailand
