Embodiment

[0059] figure 1 The structure of the apparatus of the present invention is shown. A rotary stones three-axis dry wet circulation test device, including a rotary three-axis, an air circulation system 13, a liquid circulation system 17, a sound emission system, a CT device 23, and a computer control system 24.

[0060] The rotary three-axis includes a pressure chamber 3 and a rotatable three-axis container 4 disposed in the pressure chamber 3.

[0061] The three-axis container 4 is provided with a drain exhaust pipe 10 and passes through a three-axis housing base. After the exit is connected to the air circulation system 13 and the liquid circulating system 17, respectively, after the cycle, the gas pipe 14 is performed, respectively. The water pipe 16 is coupled to the top of a triplet container.

[0062] The outer wall of the triaxial container is a rubber film 5. The acoustic emission system includes an acoustic transmitting sensor 30 and an acoustic emission control system 29; ...

Abstract

The invention discloses a rotary rock-fill triaxial dry-wet cycle test device and a test method. The device comprises a rotary triaxial apparatus, an air circulation system, a liquid circulation system, an acoustic emission system, a CT device and a computer control system. A pipeline is arranged at the bottom of a triaxial container and penetrates out of the shell base of the triaxial apparatus, and an outlet is communicated with the air circulation system and the liquid circulation system after being branched and is communicated with the top of the triaxial apparatus container after being circulated. A pressure chamber is provided with a pressure pipe and is controlled by a pressure control system; and a loading rod, the pressure control system, the CT device and the acoustic emission system are all connected with the computer control system. According to the test device, through coupling of the CT device and the acoustic emission device, rockfill particles can be automatically scanned, research on position changes and crushing conditions of the rockfill particles in a three-axis stress state after dry-wet circulation is facilitated, and monitoring of ion exchange reaction of rockfill particle materials and water in the dry-wet circulation process is facilitated.

Description

Technical field [0001] The present invention belongs to the field of geotechnical engineering, in particular to a rotary rockfill triaxial wet cycle test apparatus and a test method. Background technique [0002] Rockfill it is widely used in the construction of rockfill dam. With the further development of hydroelectric energy, construction of rockfill dam gradually to 300m level development from the dam height of 200m, an increasing number of high rockfill dam is being planned or under construction, as-built Xiaolangdi sloping clay core rockfill dam (160m), a natural bridge concrete faced rockfill dam (178m), Dadu river Falls ditch gravelly soil core rockfill dam (186m), Shuibuya concrete face rockfill dam (233m), Dadu Changheba core rockfill dam (240m), Nuozhadu gravelly soil core rockfill dam (261.5m); under construction or proposed has Shek Kip Aksu River concrete faced rockfill dam (247m), two Yalong River estuary gravel earth core rockfill dam (295m), Dadu Shuangjiangkou g...
