dcterms.abstractThe method of measuring length and mass of brad and pile includes the following steps: setting sensors on the sensing optical fiber; embedding the fiber axially inside the pile or brad, with the fiber being in the same arranged length as the pile or brad; connecting the fiber with to the light source and the reflected wave receiver; connecting the reflected wave receiver connected successively to the data collecting recorder and the data treating circuit; applying axial load to the exposed head of the pile or brad with some loading unit; obtaining the physical quantity for calculating the strain of the sensor under the action of the axial load with the reflected wave receiver; and calculating the strain distribution, length and mass of the pile or brad with the physical quantity in the data treating circuit. The present invention has wide measurement application, high reliability, low cost, high electromagnetic interference resistance and other advantages.-
dcterms.abstract本发明提供一种测量土钉与桩的长度与质量的方法,包括以下步骤:在感测光纤上设置多个传感器;将感测光纤沿轴向嵌置在被测桩或土钉中,其中,感测光纤的布置长度与所述桩或土钉的长度相同;将感测光纤分别与光源和反射波接收装置相连接;将反射波接收装置与数据收集记录器、数据处理电路依次连接;使用加载装置在暴露在外面的土钉或桩的头部施加轴向负荷;由反射波接收装置得到用于计算传感器在轴向负荷的作用下的应变(或局部两点长度变化)的物理量;数据处理电路利用所述物理量得到土钉或桩的应变分布、长度与质量。本发明能够广泛适用于对各种类型的土钉或桩的长度与质量的测量,并且具有可靠性高、成本低、抗电磁干扰、抗腐蚀以及便于使用的优点。-
