Abstract

The invention discloses an aeolian sand anchor rod drawing test device and a test method thereof. The test device comprises a base, wherein a test box for accommodating aeolian sand is arranged in thebase, a vibration loading device for carrying out vibration loading on the test box is arranged in the base, a liftable stand column telescopic sleeve is arranged on the base, a counter-force cross beam is arranged on the stand column telescopic sleeve, and a rotating screwing-in assembly for rotating to screw an anchor rod into the aeolian sand is arranged at the lower end of the counter-force cross beam. The test method comprises the following steps: wind-blown sand is scattered and vibrated to be compact, a rotary screwing-in assembly and a fixed anchor rod are installed, the anchor rod isinserted into the vibrated wind-blown sand in a rotating mode, vibration input is loaded, a drawing test is conducted, and the test is completed. The vibration load is applied to the soil body aroundthe anchor rod so that the actual stress state of the soil body is effectively simulated; meanwhile, the dynamic loading device system is arranged at the counter-force cross beam so that dynamic drawing of the anchor rod can be realized, and the stress and deformation conditions of the anchor rod in actual engineering are reflected more truly.

Description

technical field [0001] The invention belongs to the technical field of geotechnical anchoring engineering, and in particular relates to an aeolian sand bolt pulling test device and a test method thereof. Background technique [0002] Nowadays, the density of the railway network in Northwest my country has increased significantly, and the newly built heavy-haul railway will inevitably cross the desert and Gobi. Due to the high fluidity of the sandy soil in the Gobi area, it is difficult to realize the key technologies such as hole forming and grouting in the traditional anchoring process. At the same time, the vibration load generated by the heavy-duty railway train has an extremely complicated effect on the anchorage performance of the anchor. The train vibration load generated during the passage of heavy-duty trains, on the one hand, disturbs the in-situ anchored sandy soil and changes the state of the soil, and on the other hand, changes the anchoring mechanism of the anch...
