Production method of fracture formation scale model

摘要

PURPOSE:To sufficiently simulate a structural movement in an object area by accumulating a dried powder mixture with which cement is mixed in a wooden case wherein moving platens are disposed to form fractures, and, thereafter, hardening the layer of the powder mixture by supplying water into the wooden case. CONSTITUTION:A wooden case 1 is mounted in an experimental equipment body 4 wherein lifting devices 3 ... are provided, and a dried powder mixture 8 is accumulated in the wooden case 1. The mixture of silica sand and ordinary Portland cement is used as said dried powder mixture. Plaster blocks 7 ...disposed to the lifting devices 3 ... are moved upward, stopped and moved downward according to the assumed pattern of a structural movement in an object area, and, by this method, the upheaval, rest and depression of the accumulated dried powder mixture 8 are repeated to cause fractures 9 ... to form. Thereafter, gauze 11, 11 is applied between the wooden case 1 and water tanks 10, 10 disposed at both sides of the wooden case 1, respectively, to supply water in the water tank 10 into the wooden case 1 by utilizing capillarity so as to obtain a scale model 12 in a temporarily hardened state.
