Abstract

The invention discloses a horizontal load loading device for field tests of civil engineering, which comprises a pile foundation, a vertical threaded steel pre-buried in the pile foundation, a connecting sleeve, a shear keyway, a prefabricated pier segment, a horizontal Reserved tunnels, vertical reserved tunnels, shear keys, threaded steel two, actuators, threaded rods; the present invention builds the reaction force pier body on the foundation of the bored pile, and utilizes the horizontal pier body arranged on the pier body segment Reserve a hole and install the actuator to the design height. The invention can meet the horizontal load loading requirements of the civil engineering field test, and accelerates the construction speed of the loading device by using the prefabricated pier body segments, reducing the difficulty of field construction. The device can flexibly adjust the loading height of the horizontal load by changing the installation position of the actuator, so as to meet the test requirements of different models. In addition, the device of the present invention can change the installation angle of the pier, and then use the same pile foundation to test multiple models, share the construction cost of the device, and reduce the test input.

Description

technical field [0001] The invention belongs to the technical field of load test loading, and in particular relates to a horizontal load loading device for field tests of civil engineering. Background technique [0002] Soil-foundation-structure interaction is a major research topic in civil engineering, which has attracted extensive attention and research at home and abroad for decades. The design and calculation of structures such as traditional buildings and bridges is based on the assumption of a rigid foundation, and the soil, foundation, and structure are regarded as discrete independent units for static force balance analysis and calculation. However, for the design of large complex structures, it is unreasonable to continue to use the traditional rigid foundation assumption. Research results in recent years have confirmed that soil, foundation, and structure are interconnected and affect each other, and coupling analysis should be carried out as a whole. Soil-found...
