Abstract

The invention provides a failure testing system and method for anti-slide piles in side slope prevention engineering, and relates to the technical field of the side slope prevention engineering. The failure testing system comprises a side slope physical model, and an anti-slide pile model for side slope prevention is arranged in the side slope physical model. By installing detection systems in theside slope physical model and the anti-slide pile model, and simultaneously connecting a dynamic load loading system with a sliding body in the side slope physical model, the dynamic load loading system is used for driving the sliding body to continuously move in a reciprocating mode to simulate real geological disasters, such as the vibration situation of a side slope moving due to vibration when an earthquake occurs. The detection systems are used for collecting data of the anti-slide pile model and the side slope physical model in the vibration failure process and generating data. The failure testing system and method can explore the failure process of the anti-slide piles due to the vibration in the side slope prevention engineering, provide the anti-vibration improvement direction for the actual side slope prevention engineering, and have the advantages such as simple operation, low testing cost and short testing period.

Description

technical field [0001] The invention relates to the technical field of slope prevention and control engineering, in particular to a failure test system for anti-slide piles in slope prevention and control engineering and a failure test method for anti-slide piles in slope prevention and control engineering. Background technique [0002] The interaction between slope rock and soil mass and prevention engineering under earthquake is very complex. Understanding the failure process and state of slope prevention system under earthquake is of great significance to slope prevention engineering, which can provide improvement for people's actual slope prevention and control. Orientation and prevention basis. [0003] At present, the main methods for studying the engineering structure of slope prevention and control are numerical simulation and physical simulation. Numerical simulation is relatively simple and requires less investment, but its calculation accuracy mainly depends on t...
