摘要
Abstract
Adopting the grading cyclic loading method in each bearing unit of dispersed pressure anchor cable, the changing law of internal force of each unit is studied by new geological mechanics model test. According to the test methods and the state of force of the dispersed pressure anchor cable, the elastic theoretical solution which is under the conditions of grading cyclic loading and based on the Mohr-Coulomb criterion is deduced. The test results show that, under the conditions of soft rock and silty soil, the strain and shear stress distribution of the former grouting body is relatively more concentrated, the influence between units is relatively minor during the loading process. And the elastic theoretical solution based on the Mohr-Coulomb criterion can describe the strain and shear stress distribution rule of grouting body better after grading cyclic loading. The research results have a good reference value for correctly analyzing reinforcing mechanism of the dispersed pressure anchor cable and engineering design.关键词
