Group anchor effect model test device and detection method

Abstract

The invention discloses a group anchor effect model test device and a detection method. The device comprises a model box, a simulated stratum system is arranged in the model box, a group anchor systemis arranged on one side of the model box, the group anchor system penetrates through the simulated stratum system in the model box, a load loading system is arranged above the model box, an anchor rod detection system is arranged on the group anchor system, and the anchor rod detection system is connected with a detection control system. According to the invention, an existing group anchor detection device and detection method are improved, and the test precision is improved; the research on influence factors of the group anchor effect is expanded and perfected, for example, the position relation between a sliding surface and an anchor rod, the spatial position form between the anchor rods, the angle, the vertical distance and the like, the soil stress form and other factors are integrally considered such that the group anchor effect coefficient obtained through a test is more accurate, and the invention provides a group anchor effect detection method based on an intelligent jack / intelligent loading system and dynamic action such as vibration load.

Description

technical field [0001] The invention relates to the field of bolt system detection, in particular to a group anchor effect model test device and a detection method. Background technique [0002] The bolt support system has been widely used in the field of civil engineering and transportation because of its economical safety, flexibility and convenience, and less disturbance to the construction environment, especially in the stable support of surrounding rocks in slopes, tunnels, foundation pits, and underground chambers. It is favored in engineering such as protection. With the application of the bolt support system, the system presents the characteristics of clustering, systematization and structure. In order to ensure the safe operation of the bolt system, the model test of the bolt system has been developed. At home and abroad, the research on the single anchor test is relatively in-depth, and a relatively complete test method and evaluation index have been formed. For ...
