Abstract

The invention discloses a test device and a test method for testing kinetic shear characteristics between pipe piles and grouting soil bodies. The test device comprises a vibration platform, a pipe pile model test box, a loading mechanism and a monitoring system, wherein the pipe pile model test box comprises a steel bottom plate, stacked steel frames, a limiting mechanism, pipe piles arranged in the steel frames, and a sandy oil body; guide chutes are formed between the steel frames; balls are arranged on the guide chutes; hard soil is spread on the steel bottom plate; the part between the pipe piles and the sandy oil body is filled with cement paste; sealing films are arranged on the inner walls of the steel frames; and the monitoring system comprises a displacement sensor, a strain rosette group arranged on the outer surfaces of the pipe piles, and a pressure box arranged in the sandy oil body. According to the device and the method disclosed by the invention, the box wall boundary influence can be well eliminated, the problem that a scale effect and a test model similarity ratio relationship are difficult to determine is solved, the test results are accurate, reasonable and reliable, and reliable basic data is provided for theoretical analysis and engineering practice.

Description

Technical field [0001] The invention belongs to the technical field of civil engineering test devices, and specifically relates to a test device and method for testing dynamic shear characteristics between pipe piles and grouting soil. Background technique [0002] Since my country introduced and used prestressed concrete pipe piles in large quantities, it has not only saved a large amount of various building materials, energy and funds, but also greatly shortened the construction period of the project. Pipe piles are a common foundation form of buildings, mainly used for compressive, pull-out and horizontal resistance of buildings. Because the high-strength pre-stressed concrete pipe pile consumes less building materials, the factory production efficiency is high, the pile quality is good, the strength is high, and it is resistant to construction. Therefore, in recent years, with the rapid development of world economic construction, the concept of energy conservation and enviro...
