Abstract

The invention discloses a verification method of a back pressure unloading type shed tunnel structure design, and the verification method of the back pressure unloading type shed tunnel structure design aims at a back pressure unloading type shed tunnel structure in a design stage, and comprises the steps of carrying out falling stone stress analysis on the designed back pressure unloading type shed tunnel structure and carrying out gravity center point position analysis after falling stone accumulation. When the counter-pressure unloading type shed tunnel structure meets the falling stone stress analysis and the gravity center point position analysis after falling stone accumulation at the same time, the counter-pressure unloading type shed tunnel structure is safe, and otherwise, when the counter-pressure unloading type shed tunnel structure does not meet any condition, the counter-pressure unloading type shed tunnel structure has the safety problem. By means of the verification method for the back pressure unloading type shed tunnel structure design, safety verification can be conducted on the inclined cantilever type shed tunnel structure in the design stage, and then the safety problem in practical application is avoided.

Description

technical field [0001] The invention relates to the technical field of highway engineering, in particular to a verification method for the structural design of a back-pressure unloading shed. Background technique [0002] As one of the most effective and common engineering technologies for the prevention and control of rolling rocks, shed caves have been widely used in the prevention and control of rockfall on mountain roads. The existing forms of sheds include arched sheds, beam-slab sheds, and cantilevered sheds. Among them, the cantilever shed can be used in the section where there is no foundation construction condition on one side of the line or the foundation condition is poor but the foundation condition on the corresponding side is relatively good. The cantilevered sheds commonly used at present usually have cantilever beams that are orthogonal to the vertical walls. When a rockfall occurs, the cantilever end of the beams tends to accumulate a large amount of fallin...
