介绍实验室研制的一种单轴静动力拉压试验仪。该仪器可对土试件施加静力拉压和周期动力荷载，测定土的静、动强度。试件的变形采用电涡位移传感器进行非接触量测，可直接测定试件中段的变形，避免端部影响。这种传感器还可用以直接量测预留缝的开裂和扩展过程，为土的断裂特性研究提供试验依据。仪器主要用于研究击实粘性土和纤维加筋土的静、动力抗拉和断裂特性
Introduce a kind of uniaxial static dynamic tension and pressure tester developed by the laboratory. The instrument can apply static tension and cyclic dynamic load to the soil test piece to determine the static and dynamic strength of the soil. The deformation of the test piece is measured by non-contact using an eddy-displacement sensor. The deformation of the mid-section of the test piece can be measured directly to avoid the influence of the end. This sensor can also be used to directly measure the cracking and expansion process of reserved seams, providing experimental basis for the study of soil fracture characteristics. The instrument is mainly used to study the static and dynamic tensile and fracture properties of compacted clay soil and fiber reinforced soil.
