Problems solved by technology

[0003] At present, the similar test devices for slopes are simple devices, and each test can only be carried out under specific parameters, which cannot realize the test of the influence of continuous changes in parameters and coupling changes of various influencing factors on slope stability. Therefore, the simple test device test It is a waste of time and materials, and it is impossible to study multiple parameters at the same time, resulting in the inability to guarantee the accuracy of test data

Abstract

The invention relates to a three-dimensional-coupling slip surface-controllable slope stability similar testing system which comprises a water level control system, a slip surface control system, a surface displacement monitoring system, a deep displacement monitoring system, a slipping force compensation servo control system, an earthquake effect control system, a reinforcing scheme monitoring system, and a data acquisition system. The system can realize surface and deep displacement monitoring during slope excavation process, and search of slope instable slip surfaces, and can determine the influence of rock and soil or weak plane (structural plane) water content on slope stability, and the influence of earthquake effect on slope stability. The system can simultaneously study the coupling influence of factors influencing slope stability; testing conditions provided by the system better accord with actual engineering conditions; the system can realize study of influence of continuous parameter change on slope stability; no individual testing with different parameters is necessary, and no individual testing with different values of the same parameter is necessary; materials are saved greatly; the testing efficiency and testing precision are improved; and the testing results are more real and reliable.

Description

technical field [0001] The invention relates to railways, highways, building foundation pits, open pit mine slopes, river banks and natural slopes. According to the International Classification of Inventions (IPC), it belongs to the fixed building department, the construction division, the stability analysis of artificial excavated slopes and natural slopes, and the technical field of research on the rationality of reinforcement schemes. Background technique [0002] The construction of infrastructure, railways, highways, and the mining of open-pit mines form artificial slopes due to the excavation of rock and soil masses. Restricted by the surrounding environment or considering the economical and reasonable requirements of construction during the construction process, slopes with different excavation slopes are often formed. The stability of these slopes is very important. Its deformation and stability directly affect the road operation, the safety of municipal constructio...
