A test method for inducing soil cracks in flood control and rescue drills

Abstract

The invention belongs to the field of simulation devices for flood control exercises, and specifically relates to a test method for inducing soil cracks during emergency flood fighting exercises. Thetest method comprises the steps that S1, a steel plate is vertically arranged, a soil filling layer is laid at the bottom of the steel plate and one side of the steel plate, the soil filling layer isa slope at the other side opposite to the steel plate, the gradient of the slope is 0.5, the other side of the steel plate is provided with a thrust mechanism, and the force applying direction of thethrust mechanism is perpendicular to the height direction of the soil filling layer; S2, an overburden layer is laid at the top end of the soil filling layer, and the thickness of the overburden layeris twice of the horizontal displacement of the soil filling layer; S3, the thrust mechanism applies a horizontal force to the soil filling layer along the horizontal direction, and the end corresponding to the steel plate of the soil filling layer has horizontal displacement along the direction of the force; and S4, the crack generating condition of the overburden layer is observed. The test method can effectively simulate the generating process of soil cracks and facilitate the prevention of cracks in emergency.

Description

technical field [0001] The invention belongs to the field of simulation devices for flood control drills, and in particular relates to a test method for inducing soil cracks during flood control drills. Background technique [0002] As an important part of my country's infrastructure construction, slope engineering has been widely used in various complex address conditions, and safety issues have always been concerned. A large number of engineering practices have shown that before the soil slope loses its stability, a large number of tensile cracks will generally appear on the top of the slope. The formation and development of tensile cracks reduce the stability of the slope, and eventually cause landslides and other disasters that cause extremely serious losses to people's lives and property. Therefore, it is of great significance to understand the hazards of cracks and carry out targeted rescue drills to improve the effectiveness of crack rescue. Contents of the inventi...
