Abstract

The invention relates to a simple plate loading test method and device based on soil reaction force. The device comprises a cross beam, a jack, a pressure-bearing plate and ribbed steel plates; two ends of the cross beam are provided with the ribbed steel plates respectively; the jack perpendicular to the cross beam is arranged right below the middle of the cross beam; the bottom of the jack is arranged on the pressure-bearing plate that is positioned on a foundation and corresponds to the middle of the cross beam. On the basis of miniaturization of the load test device, weight of soil arounda test point is used as reaction force for a counterweight, so that loading test operations are conveniently achieved. Test efficiency is improved at the premise of ensuring accuracy of foundation test results.

Description

technical field [0001] The invention relates to a flat plate load test method and device, in particular to a simple flat plate load test method and device based on soil reaction force for testing foundation bearing capacity. Background technique [0002] Load test is an in-situ test method of foundation soil, which can be used to determine the bearing capacity and deformation characteristics of rock and soil within the main influence range of stress under the bearing plate. The plate load test can be used for the following purposes: 1) Determine the characteristic value of the bearing capacity of the foundation soil, and provide a basis for evaluating the bearing capacity of the foundation soil; 2) Determine the deformation modulus of the foundation soil; 3) Determine the reaction coefficient of the foundation soil foundation bed; etc. [0003] The load test device includes a load plate, a reaction device, a force measuring device, and a deformation measuring device. Tradi...
