Abstract

The invention provides a teaching aid for calculating bearing capacity of pile group foundation according to physical deep foundation method. The teaching aid comprises a bearing platform, a foundation soil plate, a foundation model and four stress diffusion assemblies. The foundation model is a cuboid. The bearing platform and the foundation soil plate are respectively fixed on the top surface and the bottom surface of the foundation model. The lower surface of the bearing platform is provided with four mounting troughs. The positions of the four mounting troughs correspond with four top sides of the foundation model. Each stress diffusion assembly comprises a reel and a reel surface. The reel surface is trapezoidal. The upper bottom side of each reel surface is fixed in the mounting trough, and the lower bottom side is fixedly connected with the reel. The dimension of the reel is smaller than that of the mounting trough. The foundation soil plate is provided with reel fixing positions. The teaching aid simulates stress diffusion of a physical deep foundation through four stress diffusion assemblies. The reel surface is a stress diffusion surface in which an angle between each side at the top of a pile side and the horizontal direction is alpha. The force bearing condition of the pile group foundation is simulated through a physical model, thereby facilitating understanding by the student, improving teaching effect and shortening teaching time.

Description

technical field [0001] The invention relates to a teaching aid for calculating the bearing capacity of pile group foundations by a solid deep foundation method, and belongs to the technical field of foundation engineering teaching equipment. Background technique [0002] In the pile foundation teaching process of foundation engineering, the calculation of the bearing capacity of the pile group foundation is a very important link. Its calculation methods include the solid deep foundation method and the equal generation pier foundation method. Have better spatial imagination. When the number of piles in the pile group foundation exceeds 8, and the number of rows of piles exceeds 2 rows, the calculation of the pile group bearing capacity of the pile group foundation can use the solid deep foundation method. The understanding of this calculation method is directly related to the bearing capacity of the pile group foundation. Whether the design calculation of force is correct or...
