Embodiment

[0038] Such as figure 1 , figure 2 with image 3 As shown, the present embodiment provides a horizontal static load test device for CT scanning, which specifically includes a base 1, a transparent test box 2, a servo motor 5, a transmission device and a vertically arranged model pile 13, and the transparent test box 2 It is designed with an open upper end and is vertically arranged. The bottom end of the transparent test box 2 is fixedly connected to the base 1. The base 1 is used to improve the strength of the test device. The size of the specific base 1 is greater than that of the transparent test box 2. The contact surface between the test device and the CT turntable makes the test device more balanced when it is placed, and there will be no dumping. The transparent test box 2 is filled with soil samples 3, and the soil samples 3 are filled from the top of the transparent test box 2. Soil sample 3 is compacted to simulate the normal ground conditions. In addition, soil s...

Abstract

The invention relates to a horizontal static load test device for CT scanning, and a method, and belongs to the technical field of geotechnical engineering and geological engineering testing. The horizontal static load test device in the invention comprises a base, a transparent test box, a servo motor, a transmission device and a vertically arranged model pile; the transparent test box is filledwith a soil sample; a vertically arranged transparent support column is arranged at one side of the transparent test box; the top of the transparent support column is fixedly connected with the servomotor; the output end of the servo motor is fixedly connected with the top of the model pile through the transmission device; multiple strain gages are arranged on the outer wall of the model pile; and a data acquirer is also fixedly arranged at the side edge of the transparent support column. The test device in the invention has the benefits that: the test device can be used for monitoring the horizontal resistance of the soil sample at the side of the model pile and the horizontal load of the model pile, so that a p-y curve is obtained; and, the test device can be used for scanning by beingput on an industrial CT turntable, so that deformation of the soil sample and evolution of a shear zone can be observed.

Description

technical field [0001] The invention belongs to the technical field of geotechnical engineering and geological engineering testing, and in particular relates to a horizontal static load test device and method for CT scanning. Background technique [0002] Structures such as bridges, ports and high-rise buildings are often subjected to horizontal loads such as earthquakes, strong winds, surges and collisions. Under the horizontal load, the soil is subjected to the load transmitted by the pile foundation to generate stress and strain; when the horizontal load is large, the soil will generate excessive internal force and cause damage or destruction. [0003] The current experimental research only simply applies horizontal loads, and hardly introduces effective visualization means to observe the real failure mode inside the soil. It can only be calculated and analyzed based on the assumed failure model. Therefore, it is necessary to use the non-destructive testing technology of...
