Embodiment Construction

[0055] combine figure 1 As shown, in the carrying system, the upper part of the ladder room 15 is flush with the upper part of the operating platform 16 and connected outside the framework 18 . The whole bearing system is installed on the right side of the main body system of the experiment, and is connected to the right surface of the water tank 6, but need not be fixed thereto.

[0056] Main system: one of the slopes 1 and the left short side of the horizontal base 2 are connected by 9 movable articulated joints, and the distance between adjacent articulated joints is 25cm. Two rollers 19 are installed on the right short side of the other slope 1 ', which are respectively 0.5m away from the midpoint of the short side at the bottom of the right slope 4'. The top of the left slope 4 and the lower surface of the right slope 4' can connect and disassemble the two slopes through 9 movable hinged joints, and the distance between adjacent hinged joints is 25cm. The four corners o...

Abstract

The invention discloses a physical model for longitudinal-penetration landslide geological disasters of oil and gas pipelines and an experimental method. The physical model comprises five parts including an experimental model main body structure, a rainfall mechanism, an observation mechanism, a pipeline mechanism and a bearing mechanism. By virtue of the efficient cooperation among the experimental model main body structure, the rainfall mechanism, the observation mechanism and the pipeline mechanism, the landslide state of a landslide mass is influenced by changing the rainfall degree, and then the damage condition of the landslide mass on pipelines at different states is simulated, so that the damage law of the oil and gas pipelines which are distributed in a longitudinal penetration manner is obtained, and the powerful support is provided for the selection of field protection measures of the oil and gas pipelines.

Description

Technical field: [0001] The present invention relates to a geotechnical engineering model test system and its test method, in particular to a landslide physical model system and its test method for oil and gas pipelines passing through landslides, which fills the gaps in related fields and plays an important auxiliary role in relevant scientific research . Background technique: [0002] Oil and gas pipelines inevitably need to be laid in slope formations due to reasons such as routes. When the slope angle is not large, considering economic factors, it is necessary to arrange oil and gas pipelines along the slope to the top of the slope first, and then turn to the bottom of the slope after reaching the top of the slope. When encountering geological disasters, oil and gas pipelines are often buckled and damaged, resulting in Huge property loss and severe environmental damage. Therefore, it is very important to study the impact of landslide geological disasters on the deforma...
