Description

Technical field: [0001] The invention relates to the technical fields of road engineering, railway engineering, and geotechnical engineering, in particular to an anchor-pull type retaining wall model test device and test method. Background technique: [0002] With the increasing shortage of arable land resources in our country, land resources in the process of highway construction are becoming more and more precious, and the technology of replacing high embankment slopes with retaining walls has attracted extensive attention from the engineering community. In order to improve the anti-tilting and anti-sliding stability of the retaining wall, the reinforced retaining wall structure has become a newly developed retaining wall structure with good application effects. However, because its force characteristics are significantly different from ordinary retaining walls, how to establish a reasonable mechanical calculation model has become a hot issue in the engineering community. Mode...
