摘要： Fiber optic sensors are used to monitor the integrity of a subsurface concrete structure such as a pile or diaphragm wall. A fiber optic sensor array (48) is attached to a reinforcement or framework assembly (20) for the subsurface concrete structure. Concrete is applied to surround the reinforcement or framework assembly (20) and fiber optic sensor array (48). The fiber optic sensor array (48) is then used to collect temperature data during hydration of the subsurface concrete structure. The temperature data is monitored in real time to determine differentials across the structure, indicative of a problem within the structure.

摘要： A new hammering system with electromagnetic power for dynamic pile testing. The basic working principle of the hammering system is as follows: when an internal coil is energized, a magnetic force is generated to attract tightly, via a magnetic conduction panel, an adaptive weight hammer disposed in contact with the surface of the panel; when the internal coil is de-energized, demagnetization occurs, and the weight hammer falls instantaneously to impact the pile top, thereby achieving the effects of a stable weight hammer and quick attraction and falling of the hammer. A clamping scale is arranged inside an adjustment section of a guide frame. A falling height of the weight hammer may be selected arbitrarily.

摘要： Method of design and manufacturing concrete structures subjected to relevant cyclic loads along their service lives, as wind towers, and a fatigue testing machine. The method consists on the design of concrete structures conditioned by cyclic loads considering a fatigue strength value specified by the project as one of the main design parameters, which will be verified during the manufacturing phase as one of the control parameters of the quality assurance plan by performing fatigue strength test on concrete samples representative of the concrete structural elements produced on said manufacturing phase. The method allows to decouple the concrete fatigue strength from the compressive strength of the material, which is why includes a verification of the fatigue strength as a part of a quality assurance plan of production according to a new developed procedure.

摘要： A soil stabilization system for a structure can include a stem wall and floor slab disposed within a perimeter of the stem wall. An aggregate base course (ABC) layer can be disposed within a perimeter of the stem wall and below the floor slab. A ventilation opening can extend to the ABC layer, and an air exhaust system can extend between the ABC layer and an exterior of the structure. A method of soil stabilization for a structure can include measuring a moisture content of an expansive soil below a structure, drawing dry air through the ABC layer and over a surface of an expansive soil. Moisture can be removed from the expansive soil into the dry air by evaporation to create moist air, and moist air can be evacuated at an exterior of the structure.

摘要： A load measuring system for measuring the loads on a foundation for wind turbines is disclosed. A load measuring device is mounted on a rock anchor pad for a turbine and measures the loads on the anchor. Signals from the load measuring device are transmitted to a remote location. The load measuring device is installed on selected rock anchor pads, distributed evenly about the foundation pad. The signals from the load measuring are transmitted to a control station at a remote location, thereby enabling continuous monitoring of the loading conditions on the rock anchors. The signals from a plurality of load measuring systems may be transmitted to the control station, so as to allow monitoring of a group of wind turbine foundation pads at a single location.
