Abstract

The invention provides a method for manufacturing an airbag for plate loading test of a foundation. The method comprises the following steps: cutting to form a stainless steel outer frame; taking a high-strength flexible impervious material as an airbag material, and cutting the material; sleeving the cut high-strength flexible impervious material by the stainless steel outer frame, enabling the bottom surface of the high-strength flexible impervious material to be consistent with the stainless steel outer frame, and after outwardly turning the high-strength flexible impervious material from the stainless steel outer frame, bonding the high-strength flexible impervious material onto the upper surface of the stainless steel outer frame to form the airbag; filling four corners on the inner side of the air bag to form four supports; and after solidification of a filler filling the four corners on the inner side of the airbag, stacking filler on the surface (four peripheries) of the outwardly turned high-strength flexible impervious material and on the four supports, covering with a stainless steel bearing plate, taking down the stainless steel bearing plate after solidification of the filler, and trimming the filler extruded out of the periphery of the airbag. The method can solve the problem that the critical edge pressure and the deformation modulus of the foundation, which are tested by plate loading test of the foundation, have big errors.

Description

technical field [0001] The invention relates to the technical field of airbags that can be used for foundation testing, and more specifically, relates to a design and manufacture of an airbag for foundation plate load tests, which can more accurately measure the foundation's plastic load and deformation modulus. Background technique [0002] The foundation plate load test is a widely carried out in-situ test in the foundation test. The foundation plate load test can measure the immediate plastic load, ultimate load and deformation modulus of the foundation soil. At present, the bearing plates used in the plate load test are all thick stainless steel plates. Under the central load, the settlement of the bottom of the plate is equal, and the pressure distribution at the bottom of the plate is very complicated. Therefore, the measured plastic load and deformation modulus of the foundation will have large errors. . In order to test the immediate plastic load and deformation mod...
