This invention belongs to the field of geological engineering and natural disaster simulation technology, and relates to an experimental device and method for simulating the disaster chain from a high-altitude, long-distance landslide in a cold region to a flood. The device includes a support mechanism, an acceleration mechanism, a loading vehicle, a motion mechanism, a freezing mechanism, a water tank, a water spraying mechanism, and a monitoring mechanism. The freezing and water spraying mechanisms simulate the low temperature and rainfall environment of a cold region; the acceleration mechanism drives the loading vehicle to simulate the initiation of a high-altitude landslide; the landslide mass scrapes and encases moist frozen soil samples in the motion mechanism, evolving into a debris flow under continuous water spraying; the debris flow rushes into the water tank and accumulates to form a simulated landslide dam, simulating the process of blocking a river; subsequently, under the action of upstream water, the dam collapses, triggering a simulated downstream flood. This invention can simulate and monitor the entire disaster chain of a high-altitude, long-distance landslide in a cold region – debris flow – river blockage – flood, providing an effective physical simulation technology for disaster risk assessment and prevention.

The application provides a dam-break-preventing water flow regulating system for a barrier lake, which comprises an M river and a T river, a dam is arranged at the downstream of the M river, a water regulating open channel is arranged between the M river and the T river, the water regulating open channel is arranged at an altitude between the M river and the T river, a reinforced concrete water regulating tunnel and a pressure steel pipe are further arranged, the two ends of the reinforced concrete water regulating tunnel are respectively connected with the M river and the water regulating open channel, the two ends of the pressure steel pipe are respectively connected with the water regulating open channel and the T river, and a water inlet working gate system and a water outlet working gate system are further arranged at the two ends of the reinforced concrete water regulating tunnel, so that the problem that the barrier lake formed by the earthquake has no drainage outlet and the barrier dam collapses is solved.

The utility model provides a slope anti-collapse slope structure, which is characterized in that a drainage channel is arranged at the slope toe of a seepage-stopping dam and horizontally extends along the extension direction of the seepage-stopping dam, and rock blocks are accumulated in the drainage channel and at the slope toe; the steps are arranged on the slope surface of the seepage interception dam and horizontally extend in the extending direction of the seepage interception dam; a plurality of soil engineering bags are laid along the slope surface and the steps of the seepage interception dam to form a soil engineering bag layer; drainage pipes are arranged in the seepage interception dam, one ends of the multiple drainage pipes are diverged in a fan shape, and the other ends of the multiple drainage pipes penetrate through the slope face of the seepage interception dam and stretch out of the geotechnical bag layer. The slope surface of the seepage interception dam is protected through the soil engineering bags, seepage water in the seepage interception dam is drained and guided in combination with the drainage pipe, the drainage efficiency of the seepage interception dam is remarkably improved, and therefore the seepage pressure in the seepage interception dam is reduced, and the possibility that the slope of the seepage interception dam collapses is reduced.

The application relates to the technical field of dam detection devices, and discloses a dam collapse detection device and a detection method, which comprise a dam body assembly, a detection sleeve assembly is inserted into the dam body assembly, a fixed frame is fixedly installed in the dam body assembly, a permeation driving assembly is fixedly installed on the fixed frame, and an inner transmission assembly is installed in the detection sleeve assembly. The dam collapse detection device and the detection method are characterized in that a plurality of detection sleeve assemblies are uniformly inserted into the dam body assembly, the inner transmission assembly is movably arranged in the detection sleeve assembly, when internal local leakage occurs in the dam body assembly, water from the leakage enters the detection sleeve assembly, and then the permeation driving assembly is started to rotate, so that the lower pulling block is driven to move, and then the plugging assembly is pulled and rotated to the water-impingement surface of the side surface of the dam body assembly, thereby embodying the automatic protection effect of the detection device.
