TLDR
In this paper, a mesh board consisting of a metal plate, e.g., expand metal, punching metal, plastic chemical fiber net, etc., is connected to the bottom slab of a corner retaining wall in the resultant force direction of earth pressures so that internal friction angles are increased.Abstract:
PURPOSE:To prevent the slide movement of a retaining wall by a method in which a mesh board is connected to a bottom slab in the resultant force of earth pressures, the internal friction angles of back soil is increased, and the earth pressures are reduced. CONSTITUTION:A mesh board 2 consisting of a metal plate, e.g., expand metal, punching metal, etc., plastic chemical fiber net, etc., is connected to the bottom slab 1 of a corner retaining wall in the resultant force direction of earth pressures so that internal friction angles are increased. According to the magnitude of earth pressure, the sizes and number of the boards 2 are optionally regulated. The setting of soil can thus be strengthened by the board 2, the slide movement resistance of the corner retaining wall A can be raised by frictional force acting on the board 2, and the earth pressures can be reduced. Safeness against slide movement can therefore be enhanced.read more

Method for controlling temperature of plate in continuous annealing installation
TL;DR: In this paper, the authors proposed a method to decrease the absolute value in deviation by half by changing beforehand a target temp. according to the deviation in a plate thickness that arises owing to a change in the plate thickness when the part of a plate where the thickness changes passes a cooling roll group.
