Abstract

The invention discloses a device for researching pile-soil interaction under horizontal load through transparent soil and a test method of the device. The device comprises a supporting framework and amodel slot placing plate, wherein two slide rails are arranged on a slide rail fixing plate fixed on the supporting framework; the lower surface of the model slot placing plate is fixedly equipped with slide wheels which are matched with the slide rails; a model slot and a limiting device are arranged on the upper surface of the model slot placing plate; a model pile fixing plate is connected onto the supporting framework above the model slot; a mounting hole is formed in the model pile fixing plate; a vibration wire type sensor is mounted on the side surface, approximately perpendicular to the slide rails, of the model pile; a lifting jack for pushing the model slot to slide along the slide rails is mounted on the slide rail fixing plate; a laser light source system is placed on the opposite side of the lifting jack; an image acquisition device for acquiring an image in the model slot is arranged at the perpendicular side of the laser light source system; and the image acquisition device, a helium-neon laser unit, the lifting jack and the vibration wire type sensor are connected with a controller.

Description

technical field [0001] The invention relates to the technical field of geotechnical engineering, in particular to a device and a testing method for using transparent soil to study pile-soil action under horizontal load. Background technique [0002] With the appearance of transparent soil in the 1990s and its application in geotechnical engineering physical simulation tests, it became possible to measure the internal deformation of the soil non-invasively. Transparent soil is composed of transparent solid particles and pore solution with matching refractive index, and is a transparent saturated soil obtained by discharging air. The soil has similar geotechnical properties to natural soil. Lasers can be used to form speckle fields in transparent soil, and industrial cameras can be used to take high-precision pictures. Engineering technology is a fluid velocity measurement technology developed based on image matching technology. By comparing the gray value of the picture at d...
