Embodiment 1

[0083] Example 1, such as Figure 1 to Figure 5, the model box 11 includes a model outer box 16 and a model inner box 17, the size of the model outer box 16 is a semicircle of 500mm × 700mm (R × H), and the size of the inner model box is a semicircle of 400mm × 700mm (R × H) shape. The semicircular side panels 20, 21 and bottom plate 22 of the model box 11 are all steel plates with a thickness of 4mm, wherein the outer box 16 of the model is impermeable, and the semicircular side panels of the inner box 17 of the model have water permeable holes, and the water permeability is better; the front of the model box 11 A plexiglass plate 19 with a thickness of 10mm is inserted into the rubber groove surrounding the inner wall of the model box, and the gap between the plexiglass plate and the model box is sealed with glass glue; The scale line 24 is used to control the position of the measuring points laid out and the reference datum for coordinate reading. The bottom of the semici...

Abstract

The invention relates to an indoor model device for reinforcing foundations at different underground water levels by means of dynamic compaction and a test method, and belongs to the technical field of geotechnical engineering. The indoor model device comprises a slide transverse rod, a slider, a support, drop hammer guide rods, a semicircular drop hammer, a model tank, a pore water pressure sensor or soil pressure box, permeable damping materials, a data acquisition system and a computer. The model tank comprises an inner model tank and an outer model tank, the heights of water levels are controlled by the outer model tank, the inner model tank is filled with experimental soil samples, and the pore water pressure sensor or soil pressure box is buried in the inner model tank. The indoor model device and the test method have the advantages that the test method is implemented by the aid of indoor models for reinforcing the foundations at the different underground water levels by the aid of dynamic compaction processes, deformation of the inside of soil mass at the different underground water levels under dynamic compaction effects is observed, accordingly, data of accumulation and dissipation change of pore water pressures and the like can be monitored, and various problems in the aspects of effective reinforcement depths of existing foundations at different underground water levels, pore water pressure increase and dissipation laws, construction processes and the like of existing dynamic compaction processes for reinforcing the existing foundations can be effectively solved.

Description

technical field [0001] The invention belongs to the technical field of geotechnical engineering, and in particular relates to an indoor model device and a testing method for dynamic tamping to reinforce foundations with different underground water levels. Background technique [0002] The dynamic tamping method to strengthen the foundation is a foundation reinforcement method pioneered by the French Menard Technology Company in 1969, also known as the dynamic consolidation method. This method has the advantages of wide application range, simple equipment, material saving, short construction period and low cost, so it has been promoted all over the country soon after it was introduced into our country. At present, there are researches on the reinforcement mechanism, effective reinforcement depth, pore water pressure growth and dissipation law of dynamic compaction at home and abroad. Among them, there are few studies on the law of pore water pressure growth and dissipation i...
