Abstract

The invention relates to a test tank for water-level soaking stability of a dam, in particular to a test tank for high-water-level soaking stability of a dam, and aims to solve problems of difficulty in provision of constant water levels and difficulty in control on water leveling falling speeds in existing dam stability test devices, difficulty in monitoring of dam seepage fields and difficulty in monitoring of dam slope failure and instability changes. The test tank comprises a water pump, a water supply pipe, a balance water tank, an overflow pipe, a water adjusting device water outlet pipe, a hydraulic lifting device, a connecting pipe, a water inlet pipe, a test tank body, a track, an ultrasonic automatic terrain measurement and analysis system, an upstream organic glass sieve plate, a ruler, an upstream inserting groove, an upstream earth retaining plate, a piezometric pipe, a downstream inserting groove, a downstream earth retaining plate, a downstream organic glass sieve plate, an angle steel support, water discharge pipes, valves and water meters. With the test tank, water conservancy conditions such as the constant water levels, control on the water leveling falling speeds and the like can be provided, and pore water pressure and seepage lines inside the dam are monitored. The test tank for the high-water-level soaking stability of the dam can be obtained.

Description

technical field [0001] The invention relates to a dam water level immersion stability test tank. Background technique [0002] Dangerous water conservancy conditions such as long-term high water level immersion and rapid drop of river water level have led to occasional embankment slope instability, which has a profound lesson in embankment management in our country. Therefore, the study of the impact of hazardous hydraulic conditions on the stability of dams has a long history. In order to simulate the change process of embankment seepage field and slope failure and instability under dangerous hydraulic conditions such as long-term high water level immersion and water level drop, and to explore the mechanism of embankment slope stability, an experimental device for high water level immersion stability of embankments was developed. Contents of the invention [0003] The purpose of the present invention is to solve the problems of difficulty in providing a constant water le...
