Abstract:
Disclosed is a composite hydrological monitoring system, in which a counterweight component and a test component are respectively connected to both opposite ends of a strip and a plurality of sensors are disposed at different vertical positions. Accordingly, the scour depth can be measured by sensing the location of the counterweight component, whereas the water level and/or flow velocity can be determined by signals from the sensors. When the counterweight component moves downward with sinking of the riverbed, the strip would be pulled down and thus causes the test component to present a change in mechanical energy. Accordingly, the sinking depth can be measured by sensing the change of the mechanical energy. Additionally, since the water level variation would cause signal changes of the sensors arranged in a row along a vertical direction, the change of water level can be determined accordingly.

Abstract:
The present invention relates to a sensing system and a sensing method using the same. The sensing system includes at least one tested unit and an optical fiber measuring unit. The tested unit includes a container, a strain arm and a float. The container can be filled with a fluid, and the strain arm is connected with the float and combined with a measuring portion of the optical fiber measuring unit. When the container is disposed on a body of interest, the surface inclination or settlement of the body of interest would cause changes of buoyant force on the floating element and induce bending deformation of the strain arm. Accordingly, the surface deformation of the body of interest can be determined by detecting the bending deformation of the strain arm using the measuring portion combined with the strain arm.
Abstract:
A precast segment suitable for block-stacking concept is disclosed. The precast segment includes a first surface, an opposite second surface, plural through holes, and plural male-female connecting sets. The through holes extend from the first surface and toward the second surface to communicate between the first surface and the second surface. Each male-female connecting set includes a shear key and a joint hole, wherein the shear key protrudes from one of the first surface and the second surface to serve as a male connecting unit, and the joint hole is formed in the other of the first surface and the second surface to serve as a female connecting unit. Accordingly, the precast segments can be block-stacked by mortise-and-tenon joints to construct a bridge pier system. Compared to the conventional construction methodology, the present invention can enhance the efficiency of segment fabrication and avoid high prestress force.
