Horizontal bearing characteristics test model for prestressed concrete pipe piles and modeling method

Abstract

The invention discloses a horizontal bearing characteristics test model for prestressed concrete pipe piles and a modeling method. The horizontal bearing characteristics test model comprises a model tank, a carrying platform used for carrying a model pile is arranged in the model tank, the upper end of the model pile is embedded into the carrying platform, a vertical loading system connected with a counter-force frame and applying vertical force on the carrying platform is arranged above the model tank, a horizontal loading system connected with the model tank and applying horizontal force on the carrying platform is arranged on the inner side of the model tank, and each of the carrying platform, the model pile and the loading systems is provided with a monitor. The horizontal bearing characteristics test model can well control requirements for load conditions of pile foundation load test, more really simulate practical working conditions of the pile foundation, and is a test device for researching bearing characteristics of a simple pipe pile and a group of pipe piles under the action of horizontal load.

Description

technical field [0001] The invention relates to a civil engineering test model and method, in particular to a load-bearing characteristic test model and method of prestressed concrete pipe piles in building structures. Background technique [0002] The research on the horizontal bearing characteristics of prestressed concrete pipe piles mainly includes the research on the horizontal bearing characteristics of single pipe piles, the horizontal bearing characteristics of pipe pile groups, and the horizontal bearing characteristics of pipe pile groups under vertical loads. Since the pile foundation is an underground project, there are many uncertain factors, and the field test is affected by the construction period, environmental factors and human factors of the project, so it is difficult to comprehensively analyze and study the bearing characteristics of the pile foundation under multiple working conditions. Therefore, the current research on pile foundation mainly relies on ...
