Problems solved by technology

However, most of the research focuses on the seepage failure test of the embankment foundation and the burst failure test of the embankment. There are few experimental studies on the evolution and interaction of seepage and stability of the embankment driven by the hydraulic environment, and mos...

Abstract

The invention discloses an embankment service state evolution characteristic observing device under hydraulic driving. The device comprises a device trough. A soil embankment is arranged in the devicetrough. Tempered glass is arranged on one side of the device trough. A water stop is arranged between the tempered glass and the soil embankment. A pressure measuring tube, an inlet valve, an overflow hole and a water level gauge are arranged on the other side of the device trough. The tempered glass is provided with a drain valve and a sump. A rain spray is arranged at the top of the soil embankment. An image forming real-time tracking device is arranged outside the device trough. The image forming real-time tracking device is connected with a computer. According to the invention, various types of hydraulic environments which may be encountered in an actual embankment project are considered; rapid rise and fall of the water level, continuous high water level, different rainfall patterns,the water flow velocity and other conditions can be simulated; the changing process of seepage and stability of the embankment under the conditions can be observed and analyzed; and the seepage and stability observation and data acquisition of the embankment under different working conditions and hydraulic conditions are realized.

Description

technical field [0001] The invention relates to a device and an operation method for observing evolution characteristics of dike service conditions under hydraulic drive, and belongs to the field of water conservancy and hydropower engineering safety. Background technique [0002] my country has a long history of embankment building. According to statistics, the total number of existing dikes in my country is 294,100 km. About half of the country's population, 1 / 3 of the cultivated land and 70% of the property are protected by embankments. Restrictions in many aspects, coupled with the long history of operation of many embankments and improper management and maintenance, there are relatively prominent engineering hidden dangers in embankment projects in my country. The safety of embankments is directly related to the safety of millions of people's lives and property in the protected area and the achievements of economic construction. Therefore, it is of great significance to s...
