Problems solved by technology

[0004] Many assumptions adopted in the traditional design theory avoid the interaction between the load-bearing body and the soil to varying degrees, so the calculation method of the lateral earth pressure of the lateral load-bearing body lacks a theoretical basis, and

Abstract

The invention discloses a device for detecting pressure of translating and rotating rigid barricade soil. A sliding base plate and a sliding bracket are welded between front and rear lateral plates at the bottom and top of a box; a flange is hinged with the top end and the bottom end of a rigid baffle; the flange horizontally passes through the space between the sliding base plate and the sliding bracket; a horizontal actuator is horizontally arranged between the rigid baffle and the box; a displacement sensor is horizontally connected between the left side of the box and the rigid baffle; soil is filled in the rigid baffle and the box; a rigid pressing plate and a water bag are pressed on the top surface of the soil; the rigid pressing plate is connected with a counterforce frame; and a film type pressure sensor is arranged on the side of the rigid baffle facing to the soil. The device can meet the research requirement for the soil pressure distribution rule under different ground loading conditions and different displacement modes of the rigid barricade, and has important significance in the development of soil pressure theory and the promotion of the engineering technology level.

Description

technical field [0001] The present invention relates to the technical field of architectural and civil engineering testing and testing, in particular to a rigid retaining wall earth pressure test device that can realize translation and rotation, which is suitable for simulating active and passive earth pressure tests under different displacement modes of rigid retaining walls. It is also suitable for simulating earth pressure tests of rigid retaining walls under different loading conditions. Background technique [0002] Many structures in civil engineering, such as retaining walls, abutments, foundation pit enclosure structures, etc., support the soil and keep the soil stable. They often bear the side pressure of the soil. In order to carry out the earth pressure Relevant theoretical research requires a set of fully functional test equipment to carry out laboratory physical simulation of earth pressure. [0003] At present, the earth pressure evaluation methods widely used...
