Development of early warning criteria for landslide based on internal force calculation method of rigid piles

Increasing the section method is the commonest method in double-curved arch bridge reinforcement. In order to research on the force condition of main arch ring in double-curved arch bridge reinforcement, we use internal force superposition method and stress superposition method to deduce the stress distribution of arch ring, and make contrastive analysis on each construction stage in bridge reinforcement. Internal force superposition method is unsafe; the stress superposition meets the actual situation.

Frame Mode

In frame structure, the Supports of secondary beam are frame beams or main beams, Support Beam rotation of the secondary beam to form certain constraints. General calculation method, for edge Supports, sometimes as fixed or hinged, the so-called “method of taking no account of torsion rigid”. In such cases, intermediate supports are usually as hinged, obviously not reasonable. We consider the torsional characteristics of all supports, according to torsional stiffness of the beam support. Therefore, we can become the continuous beam mode into the frame mode, so as to simplify the calculation, analyzed the influence of the torque, and should pay attention to the problem.

In this paper, the differential element of constant-section silo wall suffering from axially symmetric load is analyzed. From the results of constant-section silo, the author derives the displacements and internal forces of variable cross-section silo. Through a specific example, this paper compares the displacements , internal forces and concrete consumption of variable cross-section silo with those of constant-section silo, and discusses the merits of variable cross-section silo.
