Abstract
The invention discloses a steel sheet pile retaining wall soil pressure testing device and a steel sheet pile retaining wall soil pressure testing method considering influences of intermediate principal stress, and belongs to the soil pressure testing technology in soil mechanics. The soil pressure testing device comprises a steel sheet pile retaining wall, a model groove, an angle control device,and a soil pressure monitoring and collecting device. The steel sheet pile retaining wall comprises four steel sheet piles, two rotatable thin rods and three fixed thin rods, wherein the four steel sheet piles are respectively a steel sheet pile I, a steel sheet pile II, a steel sheet pile III and a steel sheet pile IV, which are sequentially connected together by a locking structure to form a soil retaining wall. The steel sheet pile I and the steel sheet pile IV are respectively fixedly disposed in the side wall of the model groove through the thin fixed rods, and the tops of the two thin fixed rods disposed in the side wall of the model groove are respectively provided with an angle control device. The angle control device comprises a rotating disc and a connecting rope. The soil pressure monitoring and collecting device comprises a frequency meter and four soil pressure sensors, and the soil pressure sensor is respectively arranged on the soil retaining side of each steel sheet pile.
Description
technical field [0001] The invention relates to the technical field of soil pressure testing in soil mechanics, in particular to a soil pressure testing device and method for steel sheet pile retaining walls considering the influence of medium principal stress. Background technique [0002] Due to the obvious advantages of fast construction, small footprint and recyclable utilization of steel sheet piles, whether it is in permanent structures such as piers, retaining walls, flood embankments or temporary structures such as cofferdams, foundation pits, and flood control, Steel sheet piles are widely used, such as steel sheet pile retaining walls spliced by U-shaped steel sheet piles. As one of the important loads on the steel sheet pile retaining wall, earth pressure has a direct impact on the load transfer and stress mechanism of the steel sheet pile retaining wall. Therefore, the calculation of earth pressure is particularly important in the structural design of steel sh...
