Manufacturing method of dry karst cave, simulation system and anti-seismic safety evaluation method

The invention relates to a manufacturing method of a dry karst cave. The method comprises the following steps: positioning the position of a target karst cave by adopting seismic waves; scanning by a laser scanner to generate a laser point cloud model; processing the laser point cloud model by using...

Beschreibung
Zusammenfassung:	The invention relates to a manufacturing method of a dry karst cave. The method comprises the following steps: positioning the position of a target karst cave by adopting seismic waves; scanning by a laser scanner to generate a laser point cloud model; processing the laser point cloud model by using a computer; printing a 3D karst cave cavity boundary of a stable material to form a hollow karst cave cavity; filling the cavity of the karst cave with water, and measuring the volume of the cavity; calculating the volume of water required when the karst cave cavity is filled with ice; the volume of needed water is measured and injected into the karst cave cavity, the karst cave cavity is sealed and frozen, and the karst cave cavity in an ice state is obtained; removing the boundary of the karst cave cavity to obtain an ice-state karst cave cavity; and the karst cave cavity in the ice state is buried to a preset position, after the karst cave cavity in the ice state is melted, maintenance continues to be conducted
